    <title>question Cannot monitor impala queries on Cloudera Manager Impala Queries Tab in Support Questions</title>
    <link>https://community.cloudera.com/t5/Support-Questions/Cannot-monitor-impala-queries-on-Cloudera-Manager-Impala/m-p/287096#M212857</link>
    <description>&lt;P&gt;I got installed a new cloudera cluster with versions &lt;EM&gt;CM-6.3.1&lt;/EM&gt; and &lt;EM&gt;CDH-6.3.2&lt;/EM&gt; and now facing a problem never had with previous cloudera distributions.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Cloudera Management Services (including Cloudera Service Monitor), Impala (Sentry Enabled), and all other related processes are working fine. Individual users are able to authenticate with LDAP and can query tables to which they are authorized.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;The problem is, the queries sent and executed to impala daemons&lt;SPAN&gt;&amp;nbsp;&lt;/SPAN&gt;&lt;STRONG&gt;do not appear in the Impala Queries tab&lt;/STRONG&gt;&lt;SPAN&gt;&amp;nbsp;&lt;/SPAN&gt;in Cloudera Manager, although they can be observed in&lt;STRONG&gt; Completed Impala Queries&lt;/STRONG&gt; chart, that is, there are changes in the &lt;EM&gt;queries/second&lt;/EM&gt; metric when someone send a query, i checked the things discussed in the link below.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;A href="https://community.cloudera.com/t5/Support-Questions/Empty-Impala-queries-in-Cloudera-Manager/td-p/79812" target="_blank" rel="nofollow noopener noreferrer"&gt;https://community.cloudera.com/t5/Support-Questions/Empty-Impala-queries-in-Cloudera-Manager/td-p/79812&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;No troubles in either&lt;SPAN&gt;&amp;nbsp;&lt;/SPAN&gt;&lt;FONT face="courier new,courier,monospace"&gt;/var/log/cloudera-scm-firehose/mgmt-cmf-mgmt-SERVICEMONITOR-hostname.log.out&lt;/FONT&gt;&lt;SPAN&gt;&amp;nbsp;&lt;/SPAN&gt;or&lt;SPAN&gt;&amp;nbsp;&lt;FONT face="courier new,courier,monospace"&gt;/&lt;/FONT&gt;&lt;/SPAN&gt;&lt;FONT face="courier new,courier,monospace"&gt;var/log/cloudera-scm-server/cloudera-scm-server.log&lt;/FONT&gt; logs.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;There is enough disk space in the&lt;SPAN&gt;&amp;nbsp;&lt;/SPAN&gt;&lt;STRONG&gt;Service Monitor Storage Directory&lt;/STRONG&gt;.&lt;/P&gt;&lt;P&gt;And tried to set to different sizes from 1GB to 3GB&lt;SPAN&gt;&amp;nbsp;&lt;/SPAN&gt;&lt;STRONG&gt;Impala Storage&lt;/STRONG&gt;&lt;SPAN&gt;&amp;nbsp;&lt;/SPAN&gt;(&lt;FONT face="courier new,courier,monospace"&gt;firehose_impala_storage_bytes&lt;/FONT&gt;)&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Everything seems fine, yet there are no queries in the Cloudera Manager Impala Queries Web-UI. What might be the cause of this situation?&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Any help would be highly appreciated,&lt;/P&gt;&lt;P&gt;Thanks.&lt;/P&gt;</description>
