Minwoo -- any chance you could share some details about that Hadoop issue? Something on JIRA?

RE: Region Server does not close FD.
My team member tries to resolve this issue. And He found it is a Hadoop Issue. He tries to test purging FD. Best regards, Minwoo Kang 보낸 사람: Kang Minwoo보낸 날짜: 2017년 8월 11일 금요일 오전 11:18:58 받는 사람: user@hbase.apache.org 제목: Region Server does not close FD. Hello, HBase Users. These days, My team upgrade HBase Version up to 1.2.6 and test in our product. In the meantime, My team improves real machine Fault handling. My server is JBOD. So My team decided using data node volume failures thresholds in HDFS Feature. My team set an option that is data node volume failures thresholds. After that, My team received a call our infra team. Because they could not unmount disk because FD was still alive. So My team tracked FD, and My team found Region Server had that FD. I do not know why does Region Server not closed FD. (My team use shortcircuit.) Have you ever experienced the same problem? My team member created a Jira Issue[1]. Best regards, Minwoo Kang [1]: https://issues.apache.org/jira/browse/HBASE-18454
