[jira] [Created] (IMPALA-6432) Default rpc_negotiation_timeout_ms
may cause queries to fail on large clusters
Mostafa Mokhtar created IMPALA-6432:
---------------------------------------
Summary: Default rpc_negotiation_timeout_ms may cause queries to fail on large clusters
Key: IMPALA-6432
URL: https://issues.apache.org/jira/browse/IMPALA-6432
Project: IMPALA
Issue Type: Sub-task
Components: Distributed Exec
Affects Versions: Impala 2.11.0
Reporter: Mostafa Mokhtar
While running the stress test on a 140 node secure cluster with "default" configs queries were failing with negotiation timeouts.
With rpc_negotiation_timeout_ms=60000 queries appear to run fine, ideally we should understand why this takes very long and bump the default to a more reasonable value.
