[jira] [Created] (HDFS-7900) hbase keeps too many deleted file
descriptor
zhangshilong created HDFS-7900:
----------------------------------
Summary: hbase keeps too many deleted file descriptor
Key: HDFS-7900
URL: https://issues.apache.org/jira/browse/HDFS-7900
Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs-client
Affects Versions: 2.3.0
Environment: hadoop cdh5 2.3.0 hbase 0.98
Reporter: zhangshilong
Priority: Critical
I delete some hbase's files manually or use "rm -rf blk_xxxx" to delete the blockfile directly, but hbase keeps the file descriptor very long time.
I found these file descriptor may be kept in shortcircuitcache replicaMap，
but could not find when the file descriptor will be removed. replicaMap has no limits size for putting.
run： lsof -p pid |grep deleted
