[jira] [Created] (HBASE-22463) Some paths in HFileScannerImpl did not consider block#release which will exhaust the ByteBuffAllocator

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.
