             Summary: FSHLog - close the current WAL file in a background thread
                 Key: HBASE-24695
                 URL: https://issues.apache.org/jira/browse/HBASE-24695
             Project: HBase
          Issue Type: Improvement
            Reporter: Anoop Sam John
            Assignee: Anoop Sam John


We have this as a TODO in code already
{code}
// It is at the safe point. Swap out writer from under the blocked writer thread.
      // TODO: This is close is inline with critical section. Should happen in background?
      if (this.writer != null) {
        oldFileLen = this.writer.getLength();
        try {
          TraceUtil.addTimelineAnnotation("closing writer");
          this.writer.close();
          TraceUtil.addTimelineAnnotation("writer closed");
          this.closeErrorCount.set(0);
        }
{code}
This close call in critical section and writes are blocked. Lets move this close call into another WALCloser thread.
