I've read a lot of bugs at apache hive, tested unicode, utf-8, utf-16, some isos encodings with no luck.
Can somebody help me with that?
Thanks!
Guys from Hortonwroks helped me with that issue. Seems that it's a bug.

I was running a hive query and it is not showing any error, but data is not getting inserted, if I rerun the same query after 10mins the records are getting inserted into table
my query
insert into tablename
values(‘exr‘,‘e’,’r’,’20220909')
when I have checked the hs2 logs i found below information
hiveserver2.log:2022-06-08T05:31:32,981 INFO [HiveServer2-Background-Pool: Thread-6666]: SessionState (:()) - Status: Running (Executing on YARN cluster with App id application_55555_09090)

here
in logs for the applicationId i have fetched the logs in last line it is showing Shutting down Tez Session -- this is the problem
if i have fetched logs for application id which got inserted into the hive table the last line of logs was as below
Completed executing command(queryId=hive_4-eee-444);
so please help me with this why this issue is happening is there any reason or how to avoid this issue of Shutting down Tez Session session in yarn
Please consider the following setup.
hadoop version 2.6.4
spark version 2.1.0
OS CentOS Linux release 7.2.1511 (Core)
All software is installed on a single machine as a single node cluster, spark is installed in standalone mode.
I am trying to use Spark Thrift Server.
To start the spark thrift server I run the shell script
start-thriftserver.sh
After running the thrift server, I can run beeline command line tool and issue the following commands:
The commands run successfully:
!connect jdbc:hive2://localhost:10000 user_name '' org.apache.hive.jdbc.HiveDriver
create database testdb;
use testdb;
create table names_tab(a int, name string) row format delimited fields terminated by ' ';
My first question is where on haddop is the underlying file/folder for this table/database created?
The problem is even if hadoop is stopped using stop-all.sh, still the create table/database command is successful,
which makes me think that the table is not created on hadoop at all.
My second question is how do I tell spark where in the world is hadoop installed?
and ask spark to use hadoop as the underlying data store for all queries run from beeline.
Am I supposed to install spark in some other mode?
Thanks in advance.
My objective was to get the beeline command line utility work through Spark Thrift Server using hadoop as underlying data-store and I got it to work. My setup was like this:
Hadoop <--> Spark <--> SparkThriftServer <--> beeline
I wanted to configure spark in such a manner that it uses hadoop for all queries run at beeline command line utility.
The trick was to specify the following property in spark-defaults.xml.
spark.sql.warehouse.dir hdfs://localhost:9000/user/hive/warehouse
By default spark uses derby for both meta data and the data itself (called warehouse in spark)
In order to have spark use hadoop as warehouse I had to add this property.
Here is a sample output
./beeline
Beeline version 1.0.1 by Apache Hive

I can do all other queries in hive, but when I do a join it just gets stuck.

Its hung at this point, and it doesn't spawn any of the map reduce tasks at all. What could be wrong?
I did see this in hive.log.

There is nothing beyond this. Anyone knows how to fix this ?
Open mapred-site.xml file and add the property:
<property>
<name>mapred.child.java.opts</name>
<value>-Xmx1024m</value>
you need to increase your heap memory used by hadoop JVM
I'm using Apache hadoop 1.1.1 and Apache hbase 0.94.3.I wanted to load data from HDFS to HBASE.
I wrote pig script to serve the purpose. First i created hbase table in habse and next wrote pig script to load the data from HDFS to HBASE. But it is not loading the data into hbase table. Dont know where it's going worng.
Below is the command used to craete hbase table :
create table 'mydata','mycf'
Below is the pig script to load data from hdfs to hbase:
A = LOAD '/user/hduser/Dataparse/goodrec1.txt' USING PigStorage(',') as (c1:int, c2:chararray,c3:chararray,c4:int,c5:chararray);
STORE A INTO 'hbase://mydata'
USING org.apache.pig.backend.hadoop.hbase.HBaseStorage(
'mycf:c1,mycf:c2,mycf:c3,mycf:c4,mycf:c5');
After excecuting the script it says
2014-04-29 16:01:06,367 [main] INFO org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MapReduceLauncher - 100% complete

Please help where i'm going wrong ?
You have specified too many columns in the output to hbase. You have 5 input columns and 5 output columns, but HBaseStorage requires the first column to be the row key so there should only be 4 in the output
I am trying to read hive table using PIG script but when I run a pig code to read a table in hive its giving me following error:

Hadoop version
1.1.1
Hive version
0.9.0
Pig version
0.10.0
Pig code
a = LOAD '/user/hive/warehouse/test' USING
org.apache.pig.piggybank.storage.HiveColumnarLoader('name string');
Is it due to some version mismatch ?
Why can't you use hcatalog to access hive metadata in pig?
