Error thrown while creating table in impala using HUE.

Thanks much or your quick response, appreciate it :)
So, it means that no impala query will succeed unless the space on the Postgres System is under threshold.
Is my understanding correct?
Thank you, Waiting for your response!

Impala relies on hivemetastore for persisting table metadata. HMS inturn uses db to persist metadata. So if the db's filesystem is out of space, request from hms to persist metadata will be denied and yes if the space on the db is not freed up then request from hms will be failed and eventually impala also fails the query

Stuckup with hive now
Please help me, why this error below.Is something wrong with Hive metastore?
hive> show databases;
FAILED: SemanticException org.apache.hadoop.hive.ql.metadata.HiveException: org.apache.hadoop.hive.ql.metadata.HiveException: org.apache.thrift.transport.TTransportException: java.net.SocketException: Connection reset
Help me , thanks !

there's not much information there but it does sound like your HS2 can't connect to the HMS.
If you didn't fix the space issues for HMS then maybe HMS isn't running well.
You may find useful information in the HMS logs
