I am trying to run pig script from the hdfs but it shows error as the file does not exist.

What am I missing ?
You may use -f <script location> option and option value to run script located at HDFS path. But script location need to be absolute path as given in following syntax and example.
Syntax:
pig -f <fs.defaultFS>/<script path in hdfs>
Example:
pig -f hdfs://Foton/user/root/script.pig

I am following this document https://docs.databricks.com/data/metastores/external-hive-metastore.html#spark-configuration-options
to connect to my external hive metastore. My metastore version is 3.1.0 and followed the document.
docs.databricks.comdocs.databricks.com
External Apache Hive metastore — Databricks Documentation
Learn how to connect to external Apache Hive metastores in Databricks.

I have getting this error when trying to connect to external hive metastore
org/apache/hadoop/hive/conf/HiveConf when creating Hive client using classpath:
Please make sure that jars for your version of hive and hadoop are included in the paths passed to spark.sql.hive.metastore.jars
spark.sql.hive.metastore.jars=/databricks/hive_metastore_jars/*
When I do an ls on /databricks/hive_metastore_jars/, I can see all copied files
10:52
Do I need to copy any hive specific files and upload it in this folder?
I did exactly what was mentioned in the site
These are the contents of my hive_metastore_jars

Am I missing anything?
Strangely If I look into the cluster boot logs here is what I get
20/03/24 07:29:05 INFO Persistence: Property spark.hadoop.javax.jdo.option.ConnectionDriverName unknown - will be ignored
20/03/24 07:29:05 INFO Persistence: Property spark.hadoop.javax.jdo.option.ConnectionURL unknown - will be ignored

20/03/24 07:29:09 WARN ObjectStore: Failed to get database default, returning NoSuchObjectException
I have already set the above configurations and it shows in the logs as well
20/03/24 07:28:59 INFO SparkContext: Spark configuration:
spark.hadoop.javax.jdo.option.ConnectionDriverName=org.mariadb.jdbc.Driver
spark.hadoop.javax.jdo.option.ConnectionPassword=*********(redacted)
spark.hadoop.javax.jdo.option.ConnectionURL=*********(redacted)
spark.hadoop.javax.jdo.option.ConnectionUserName=*********(redacted)
Also version information is available in my hive metastore, I can connect to mysql and see it it shows
SCHEMA_VERSION : 3.1.0
VER_ID = 1
From the output, it looks like the jars are not copied to the "/databricks/hive_metastore_jars/" location. As mentioned in the documentation link you shared:
Set spark.sql.hive.metastore.jars set to maven
Restart the cluster with the above configuration and then check in the Spark driver logs for the message :
17/11/18 22:41:19 INFO IsolatedClientLoader: Downloaded metastore jars to <path>
From this location copy the jars to DBFS from the same cluster and then use an init script to copy the jars from DBFS to "/databricks/hive_metastore_jars/"
As I am using azure mysql there is one more step I need to perform
https://learn.microsoft.com/en-us/azure/databricks/data/metastores/external-hive-metastore
I am able to connect to Mapr Control System - MCS - port 8080 (Web - UI) but where can i see the data file i copied from my local files system.??
On the MCS Navigation Pane , I can see the below tabs but i dont see where to navigate to data folder.

Which begins a workflow, but then dies due to a collision with Jackson jars.

So from the above it seems that regardless of
oozie.action.sharelib.for.spark=spark2
in the Job.properties, YARN/Oozie is loading all of the jars including the old version of jackson into the container. I am setting --conf spark.yarn.jars=spark2/* on the spark job itself too.
So I think that Oozie is spawning a map-reduce job with all of the oozie sharelib jar. This job then spawns a new container for the Spark action which contains all the jars causing the collision. I need the spark container to only include the spark jars.
I am using an Oozie version < 4.3.1
see below fixes:
https://issues.apache.org/jira/browse/OOZIE-2606
https://issues.apache.org/jira/browse/OOZIE-2658
https://issues.apache.org/jira/browse/OOZIE-2787
https://issues.apache.org/jira/browse/OOZIE-2802
These fixes ensure that the Spark container only contains the correct Jars on the path avoiding the Jackson collision.
I was facing issues in deploying local files to hdfs and found that I should have "drwx------" for datanode and namenode.
Initial permission status of datanode and namenode in hdfs.
drwx------ 3 hduser hadoop 4096 Mar 2 16:45 datanode
drwxr-xr-x 3 hduser hadoop 4096 Mar 2 17:30 namenode
Permission of datanode is changed to 755
hduser#pradeep:~$ chmod -R 755 /usr/local/hadoop_store/hdfs/
hduser#pradeep:~$ ls -l /usr/local/hadoop_store/hdfs/
total 8
drwxr-xr-x 3 hduser hadoop 4096 Mar 2 16:45 datanode
drwxr-xr-x 3 hduser hadoop 4096 Mar 2 17:30 namenode
After initiating start-dfs.sh, datanode didn't start and permissions to datanode were restored to original state.

drwx------ 3 hduser hadoop 4096 Mar 2 22:34 datanode
drwxr-xr-x 3 hduser hadoop 4096 Mar 2 22:34 namenode
As datanode is not running i am not able to deploy data to hdfs from local file system. I couldn't understand or find any reason why the file permissions are restored to previous state only for datanode folder.
it appears the name space id generated by the NameNode is different from your DataNode.
Solution:
if you goto the path where your hadoop files are stored on the local file system.
forexample /usr/local/hadoop. go down the path to /usr/local/hadoop/tmp/dfs/name/version. copy the namespaceid and take it to the path /usr/local/hadoop/tmp/dfs/data/version , replace the namespaceid.
i hope this helps.
I want to run some application which is killed or finished (not running application).
I run application like this :
$ yarn jar /usr/local/hadoop/share/hadoop/yarn/hadoop-yarn-applications-distributedshell-2.7.2.jar -jar /usr/local/hadoop/share/hadoop/yarn/hadoop-yarn-applications-distributedshell-2.7.2.jar -queue queueTEST01 -shell_command "vmstat 60" -container_memory 2048
and figure out that it saves two files in hdfs.

Or is here some other way?
