We have the following
We using postgresl Database as metastore (shared )
both for hive / impala .
Hue server - for data analysts
Right know we are using ORC table format.
I understand all the necessary prequist for hive delete update operations
we are managing the cluster using Clouldera Manager . My only question is where does the below configuration go in Safety valve . When they service and Client side . I am confused any help is highly appreciable man
we fire query from Hue web interface .
Client Side hive.support.concurrency – true hive.enforce.bucketing – true (Not required as of Hive 2.0) hive.exec.dynamic.partition.mode – nonstrict hive.txn.manager – org.apache.hadoop.hive.ql.lockmgr.DbTxnManager Server Side (Metastore) hive.compactor.initiator.on – true (See table below for more details) hive.compactor.worker.threads – a positive number on at least one instance of the Thrift metastore service

There are two options
1. Temporary setup. Go to Hue -> Hive query editor and set up your configuration
To get the current value, you can run it before & after setup
2. Permanent setup: As your admin to Go to Cloudera Manager -> Hive -> Configuration -> search for HiveServer2 Advanced Configuration Snippet (Safety Valve) and update the rqeuired properties as follows
Note: The Temporary setup will influence only your scripts but Permanent setup will influence all the script executions. so think twice and take the necessary action
