Zheng Hu created HBASE-22463:
--------------------------------
Summary: Some paths in HFileScannerImpl did not consider
block#release which will exhaust the ByteBuffAllocator
Key: HBASE-22463
URL: https://issues.apache.org/jira/browse/HBASE-22463
Project: HBase
Issue Type: Sub-task
Reporter: Zheng Hu
Assignee: Zheng Hu
When I debug the issue HBASE-22422, I observed that the
ByteBuffAllocator#usedBufCount will was always increasing and all direct
ByteBuffers would be exhausted, which lead to may heap allocation happen. The
comment here [1] is also related to this problem.
Check the code path, the HFileScannerImpl is the biggest suspect, so create
issue to address this.
