Excessive RAM Consumption for the Impala Catalog Due to IMPALA-2840 (Doc ID 2103028.1)

Last updated on FEBRUARY 04, 2016

Applies to:

Big Data Appliance Integrated Software - Version 4.2.0 and later
Linux x86-64

Symptoms

The Impala Catalog gets: "Out of Memory" Errors and all queries hang until Impala is restarted. Comparing the Heap used by the Impala Catalog Server in the Impala service Charts Library with the Catalog topic size observed from:
http://<Impala StateStore host>:25010/topics
indicates that the catalog is using up too much heap.
