One outcome of this is that the Master is left hanging on the RS for completion of various operations - such as region un-assignment when a table is disabled. Does it make sense to create a separate thread pool for communication between the Master and the RS? This addresses not just the case of the RPC handler threads terminating but also long-running queries or co-processor executions holding up master operations. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
