The problem that HBase stops node reporting errors and does not exist in pid

The error in stopping the HBase node is as follows:

[root@hregion92 bin] # / opt/hbase-0.98.7/bin/hbase-daemon.sh stop regionserver

No regionserver to stop because no pid file / opt/hbase-0.98.7/pids/hbase-root-regionserver.pid

The reason is that the pid file is saved in the / tmp directory by default, and the files in the / tmp directory are easy to lose

Solution: modify the storage path of the pid file in hbase-env.sh

The following text in hbase-env.sh is commented out by default, you can release it, or you can specify your own storage location:

# The directory where pid files are stored. / tmp by default.

Export HBASE_PID_DIR=/var/hadoop/pids
