Enis Soztutar updated HBASE-15295: ---------------------------------- Attachment: hbase-15295_v2.patch bq. why not add controller for access control method in ProtobufUtil? I think I've missed it when going over methods in Admin. Since they are called from AccessControlClient. Anyway, patch v2 addresses that. Attaching v2 for hadoopqa. > MutateTableAccess.multiMutate() does not get high priority causing a deadlock > ----------------------------------------------------------------------------- > > Key: HBASE-15295 > URL: https://issues.apache.org/jira/browse/HBASE-15295 > Project: HBase > Issue Type: Bug > Reporter: Enis Soztutar > Assignee: Enis Soztutar > Fix For: 2.0.0, 1.3.0, 1.2.1, 1.1.4 > > Attachments: hbase-15295_v1.patch, hbase-15295_v1.patch, > hbase-15295_v2.patch > > > We have seen this in a cluster with Phoenix secondary indexes leading to a > deadlock.
