[jira] [Created] (HBASE-7376) Acquire readLock do not apply timeout in flushcache

binlijin created HBASE-7376:
-------------------------------

             Summary: Acquire readLock do not apply timeout in flushcache
                 Key: HBASE-7376
                 URL: https://issues.apache.org/jira/browse/HBASE-7376
             Project: HBase
          Issue Type: Bug
          Components: regionserver
    Affects Versions: 0.96.0, 0.94.4
            Reporter: binlijin
             Fix For: 0.96.0, 0.94.4


{code}
HRegion
  public boolean flushcache() throws IOException {
       lock(lock.readLock());
  }
{code}
The HRegion.flushcache is called by the normal flush cache, so if we use a timeout, the MemStoreFlusher may be get a RegionTooBusyException, it is safe to do not use a timeout.
