> I could see {{listCacheDirectives()}} and {{listCachePools()}} APIs can be
> called even after the filesystem close. Instead these calls should do
> {{checkOpen}} and throws:
> {code}
> java.io.IOException: Filesystem closed
> at org.apache.hadoop.hdfs.DFSClient.checkOpen(DFSClient.java:464)
> {code}
