I have been working on Spring Boot project, I am using Flyway for database version control in this project. In migration folder there are some SQL files having "Load data local infile" Statements - referencing some CSV files.
Example:
load data local infile 'C:/Program Files (x86)/Apache Software Foundation/Tomcat 8.5/webapps/originator/WEB-INF/classes/insertData/subject.csv' INTO TABLE subject
How can I make this path relative?
I have tried
'./classes/insertData/subject.csv'
'./insertData/subject.csv'
And some other combinations also but could not fixed this issue
Error:
Caused by: java.sql.SQLException: Unable to open file '../../insertData/subject.csv'for 'LOAD DATA LOCAL INFILE' command.Due to underlying IOException:
BEGIN NESTED EXCEPTION java.io.FileNotFoundException MESSAGE:
....\insertData\subject.csv (The system cannot find the path
specified) STACKTRACE: java.io.FileNotFoundException:
....\insertData\subject.csv (The system cannot find the path
specified)
I was able to insert data into tables from CSV files within a flyway migration from a resource path. Within the migration script I used the entire path written as shown below.
LOAD DATA LOCAL INFILE './src/main/resources/<FOLDER>/<FILE>.csv' INTO TABLE <TABLE_NAME>
FIELDS TERMINATED BY ','
optionally enclosed by '"'
LINES TERMINATED BY '\r\n'
IGNORE 1 LINES;
The other statements would be dependent on your file structure I just wanted to include the entire example.
Instead of writing SQL script you can use Java-based migration to read and insert data into a table. You can use "flyway.locations" property to specify the path for java based migration in your application.properties. As flyway by default search for "./db/migration" of resources.
For further details check the https://flywaydb.org/documentation/migrations#java-based-migrations

getting below error while starting the database:-
startup
ORA-01078: failure in processing system parameters
ORA-01565: error in identifying file '+DATA/mis/PARAMETERFILE/spfile.276.967375255'

ORA-04031: unable to allocate 56 bytes of shared memory ("shared pool","unknown object","KKSSP^24","kglseshtSegs")
Your database cannot find the SPFILE (newer init.ora) within ASM with the actual system parameters or has no permissions to access it.
Either your Grid Infrastructure stack or the dbs/spfile.ora is pointing to the wrong file.
To find out what the grid infrastructure stack is using, run "srvctl" which should display the parameterfile name the database should be using
srvctl config database -d <dbname>
...
Spfile: +DATA/<dbname>/PARAMETERFILE/spfile.269.1066152225
...
Then check (as the grid user), if the file indeed is not visible (by using asmcmd):
asmcmd
ASMCMD> ls +DATA/<dbname>/PARAMETERFILE/
spfile.269.1066152225
If the name is different, then you got the issue... (and you have to point to the correct file).
If the name is correct, then it could be wrong permissions on the oracle executable(s) (check My Oracle Support):
RAC Database Can't Start: ORA-01565, ORA-17503: ksfdopn:10 Failed to open file +DATA/BPBL/spfileBPBL.ora (Doc ID 2316088.1)
I am running a small cluster in Amazone EMR in order to play with Apache Hive 2.3.5. It is my understanding that Apache Hive can import data from a remote database and have the cluster to run queries. I was following an example that is provided in Apache Hive web documentation (https://cwiki.apache.org/confluence/display/Hive/JdbcStorageHandler) and created the following code:
CREATE EXTERNAL TABLE hive_table
(
col1 int,
col2 string,
col3 date
)
STORED BY 'org.apache.hive.storage.jdbc.JdbcStorageHandler'
TBLPROPERTIES (
'hive.sql.database.type'='POSTGRES',
'hive.sql.jdbc.driver'='org.postgresql.Driver',
'hive.sql.jdbc.url'='jdbc:postgresql://<url>/<dbname>',
'hive.sql.dbcp.username'='<username>',
'hive.sql.dbcp.password'='<password>',
'hive.sql.table'='<dbtable>',
'hive.sql.dbcp.maxActive'='1'
);
But I get the following error:
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. java.lang.RuntimeException: MetaException(message:org.apache.hadoop.hive.serde2.SerDeException java.lang.IllegalArgumentException: Property hive.sql.query is required.)
According to the documentation, I need to specify either “hive.sql.table” or “hive.sql.query” to tell how to get data from jdbc database. But if I replace hive.sql.table with hive.sql.query I get the following error:
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. java.lang.RuntimeException: MetaException(message:org.apache.hadoop.hive.serde2.SerDeException java.lang.IllegalArgumentException: No enum constant org.apache.hive.storage.jdbc.conf.DatabaseType.POSTGRES)
I tried looking in the web for a solution and it doesn't look like anyone experience the same issues that I am having. Do I need to modify a config file or am I missing something critical in my code?
I think you are using a version of the jar which doesn't support POSTGRES.
Download the latest jar from this link:
http://repo1.maven.org/maven2/org/apache/hive/hive-jdbc-handler/3.1.2/hive-jdbc-handler-3.1.2.jar
Put this downloaded jar into a hdfs location.
Run hive normally.
Run command: add jar ${HDFS_PATH_TO_DOWNLOADED_JAR}
Run your create table command
I am using ODI (12.1.3.0.0). I created topology for Oracle DB which is OK and I created topology for HDFS using File technology where I think the problem is in.
DataServer for HDFS, I left JDBC driver empty, and filled JDBC Url with hdfs://remotehostname:port
Physical Schema for HDFS, I filled both Schema and Work Schema with /my/path
Then created Logical Schema and Model. After that created Datastore under the model with these definitions.
Name: TestName
Resource Name: TESTFILE.txt
File Format: Fixed
After all these, created a project and a mapping under the project.
Finally when I run the mapping I see these errors:
ODI-1217: Session Oracle2HDFSMapping_Physical_SESS (15) fails with return code ODI-1298.
ODI-1226: Step Physical_STEP fails after 1 attempt(s).

I wonder where I did it wrong?
For a file Datastore, you need to define the attributes (columns) by opening the Datastore and going on the attribute tab. If the file already exists, you can reverse-engineer the attributes and rename them and change the datatype if needed.
The error message you received for the second task mentions that the file (generated in the fist task) does not exist. So there might be a problem with the first task, probably due to the missing attributes in your datastore.

Is it possible to use file in LOCATION for external table in HIVE?
CREATE EXTERNAL TABLE table1
(
line string
)
LOCATION '/hdp_in/fd/file.txt.gz';
cause I get an error:
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. MetaException(message:Got exception: org.apache.hadoop.fs.FileAlreadyExistsException Parent path is not a directory: /hdp_in/fd/file.txt.gz file.txt.gz
at org.apache.hadoop.hdfs.server.namenode.FSDirectory.mkdirs(FSDirectory.java:1957)
(...)
Do I have to use only directories? I haven't found that info in Manual Reference...

Yes you will have to put this file in a directory and then create an external table on top of it. As per the documentation : An EXTERNAL table points to any HDFS location for its storage, rather than being stored in a folder specified by the configuration property hive.metastore.warehouse.dir
Even if you create an internal table hive by default creates a directory for it inside the hive.metastore.warehouse.dir and the same behavior is expected while creating an external table except for the fact that the default directory is not used.
I was getting the below given error, When I run the application:
Caused by: org.hibernate.exception.GenericJDBCException: could not execute native bulk manipulation query
.
.
Caused by: java.sql.SQLException: ORA-01157: cannot identify/lock data file - see DBWR trace file
ORA-01110: data file : '/fld1/fld2/mytemp_tablespace.dbf'
I tried to find out this files and came to know that there is no folders. I have ,
then created the respective folders and a new empty mytemptemp_tablespace.dbf file. But still the same error is getting over there.
Any idea why this error is happening?If it is an SQL exception it could have happened at the right beginning itself.
What I have done is, I have created a new schema and exported the db from the old to this new one.
Also how can I see or get the DBWR trace file.
This could be the result of a restored database and during the restore rman was not able to create the tempfiles because of a missing directory.
Solution is quite simple, once the directories are created, just add one or more tempfiles:
alter tablespace mytemp_tablespace add tempfile '/fld1/fld2/mytemp_tablespace01.dbf';
when the temp tablespace has it's storage, your actions can succeed.
