-------------------------------------
Summary: 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: 1.2.4, 0.98.23
Reporter: Guangxu Cheng
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.
