Ted Yu commented on HBASE-17256: -------------------------------- Is the call to purgeExpiredTasks() needed for createRPCStatus() ? > Rpc handler monitoring will be removed when the task queue is full > ------------------------------------------------------------------ > > Key: HBASE-17256 > URL: https://issues.apache.org/jira/browse/HBASE-17256 > Project: HBase > Issue Type: Bug > Affects Versions: 2.0.0, 0.98.23, 1.2.4 > Reporter: Guangxu Cheng > Attachments: HBASE-17256-v1.patch > > > The RPC handlers monitoring will displayed in the Web UI when the cluster has > just started. As time goes on, RPC handlers disappeared . > We have the RPC handlers listed as tasks and stored in CircularFifoBuffer. > CircularFifoBuffer is a first in first out buffer with a fixed size that > replaces its oldest element if full. > When we refresh the page, completed tasks will be removed from > CircularFifoBuffer. > Not refresh the page for a long time, the oldest element (RPC handlers) will > be replaced by new tasks. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
