GC benchmarking and analysis tools
----------------------------------
Key: HBASE-4812
URL: https://issues.apache.org/jira/browse/HBASE-4812
Project: HBase
Issue Type: Task
Components: io
Reporter: Jonathan Gray
Assignee: Jonathan Gray
Priority: Minor
One of the challenges of debugging GC issues is that it can take a long time to
reproduce GC pauses. Isolating the LRU block cache and benchmarking it
independently can more easily cause measurable and reproducible GC issues.
In addition, making sense of the noisy GC logs is difficult.
This may not be for commit, but I wanted to share some code and scripts I've
written to tackle these problems.
