Greetings @melmoumni    Thanks for using Cloudera Community. For now, No to HA for Catalogd. This is coming from the fact stated in [1], wherein the Catalogd Unavailability don't leads to DataLoss & they can be removed to be added on a New Host without any impact. Similarly, the Upstream JIRA [2] remains Unresolved.    Again, I shall keep the Post available for others to provide their feedback, if they have tested the same. In [2], One User share their experience, which doesn't appear to be Successful.    Regards, Smarak   [1] https://impala.apache.org/docs/build/html/topics/impala_proxy.html [2] https://issues.apache.org/jira/browse/IMPALA-2702   ...

Hello @OmarElSeihy    Thanks for using Cloudera Community. Based on the Post, your Team is receiving a Warning [1]. By default, the Role uses "/tmp" for -XX:HeapDumpPath. Your Team need to change the Value set for -XX:HeapDumpPath to a Mount, wherein your Team have Sufficient Space. Alternatively, Your Team can work on reducing the FileSystem Usage on the concerned Mount Point.  This Warning is an Alert for Cluster Admin & has no impact on any Service Usage in the Cluster.  Sharing a Screenshot showing the Config Changes required, if your Team wish to modify the HeapDump Path & the Warning Threshold (Example shown for Solr Service as used Solr in the Post Tags):   Regards, Smarak   [1] This role's Heap Dump Directory is on a filesystem with less than 10.0 GiB of its space free. /tmp ...

Hello @ganeshkumarj    Thanks for using Cloudera Community. Based on the Post, You are migrating from Cloudera Search (CDH 5.9.3) to Standalone Solr (Apache v4.10.3). As your Team mentioned, the Error points to Index (Copied manually) being on a Lucene Version higher than anticipated [1].    Your Team can confirm the LuceneVersion via "solrconfig.xml" for the Collection "sample_collection" on CDH. If LuceneVersion Match isn't feasible, ReIndexing is the Only Way forward. Yet, there are few things wherein our help in this Post would be limited: (I) CDH v5.9.3 is EoS since a long time. Internally, We have extremely limited Setup for checking further on your Team's concerns.  (II) Your Team is implementing the Migration on Standalone Solr (Apache v4.10.3). Cloudera Product Offering package Solr into Search (In CDH) & Solr (In CDP). Unfortunately, We have limited input on any Open Source Implementation outside of Cloudera Product.    Our Team would be happy to assist your Team to Migrate from CDH v5.9.3 to CDP, if required by your Team. We have Documentation (Which are Tested internally) to migrate from CDH Search to CDP Solr & your Team would get the Support assistance in any issues as well.    Regards, Smarak   [1] https://lucene.apache.org/core/7_1_0/core/org/apache/lucene/index/IndexFormatTooNewException.html   ...
