----------------------------------------------
Summary: NPE in CreateNamespaceProcedure and
DeleteNamespaceProcedure
Key: HBASE-30008
URL: https://issues.apache.org/jira/browse/HBASE-30008
Project: HBase
Issue Type: Bug
Affects Versions: 2.6.4
Reporter: Dimas Shidqi Parikesit
Currently, CreateNamespaceProcedure:setNamespaceQuota and
DeleteNamespaceProcedure:removeNamespaceQuota gets MasterQuotaManager by using
`env.getMasterServices().getMasterQuotaManager()`.
It is possible that HMaster marks itself initialized before it creates and
stores quotaManager, which can cause NPE. Oher procedures prevent this issue by
using `ProcedureSyncWait.getMasterQuotaManager(env)` which will wait for the
quotaManager to be ready.
I’ve provided a fix to use ProcedureSyncWait.getMasterQuotaManager instead of
directly getting it from the masterServices.
