Hi @syedshakir, can you clarify what query was failing this way? I suppose it was an insert query from Impala. Was it a dynamic partitioning insert?
Have you checked the Impala query profile?
Please look into the impala daemon (coordinator host) logs and check the full error message - if that's available.
You may also check if there was another insert or insert overwrite query for the same target table. From CM > Impala > Queries page you can search out queries manipulating the same table.
