Why "java.lang.UnsatisfiedLinkError: Permission denied" exception thrown while starting HBase shell?

Question

Why "java.lang.UnsatisfiedLinkError: Permission denied" exception thrown while starting HBase shell?

Answer

During HBase shell execution JRuby create temporary files under java.io.tmpdir path and default value of java.io.tmpdir is /tmp. If NOEXEC permission is set to /tmp directory then HBase shell start will fail with "java.lang.UnsatisfiedLinkError: Permission denied" exception.

So "java.io.tmpdir" must be set to a different path in HBASE_OPTS/CLIENT_GC_OPTS if NOEXEC is set to /tmp directory.
