<div class="section" id="mrs_01_1648__s5f5cf1736b464516ac4ef70788b16b9d"><h4 class="sectiontitle">Answer</h4><p id="mrs_01_1648__ae98b6645b23a4cf88a134b37e6699314">During HBase shell execution JRuby create temporary files under <span class="filepath" id="mrs_01_1648__f50ce5c6217964bdbac91ae9ddb4e30a9"><b>java.io.tmpdir</b></span> path and default value of <span class="filepath" id="mrs_01_1648__f440d0d232d0c478aade01baaae2d01f0"><b>java.io.tmpdir</b></span> is <span class="filepath" id="mrs_01_1648__f62c21d8d168a4d34a07b29e6fa5f90df"><b>/tmp</b></span>. If NOEXEC permission is set to /tmp directory then HBase shell start will fail with "java.lang.UnsatisfiedLinkError: Permission denied" exception.</p>

<p id="mrs_01_1648__a4804c08a34f74c66a42ec7cc41381d94">So "java.io.tmpdir" must be set to a different path in HBASE_OPTS/CLIENT_GC_OPTS if NOEXEC is set to /tmp directory.</p>
