							 Hi @G_B   It could be a issue with your JDK version. Compare the JDK version in your working and non-working datanodes and try to upgrade/downgrade accordingly.

							 Hi @Lorenzo_F   It could be due to the below bug -  https://issues.apache.org/jira/browse/HIVE-22981  You may need to reproduce the issue and take heap dump to confirm it.

							 Hi @MaraWang   The rebase to HBase 2.6.0 is planned for upcoming CDP releases. We recommend monitoring our release notes for updates regarding this change.

							 Hi @MaraWang   CDP uses its own downstream versions of open-source projects like Hadoop and HBase. These versions are often forked from the upstream Apache projects. After forking, Cloudera applies additional patches, enhancements, security fixes, and compatibility improvements that are necessary for enterprise-grade stability and integration across the platform.  Because of this, the specific Hadoop or HBase versions you see in CDP may not match exactly with any version listed on the official Apache Hadoop or HBase websites. Instead, Cloudera maintains and supports its own versions to ensure a tested and supported ecosystem for customers.

							 @Shelton   Have you tested this property in your environment? Neither hbase.mob.file.expired nor hbase.mob.file.expired.period properties are present in hbase.   A MOB HFile will be subject to archiving under any of the following conditions:      Any MOB HFile older than the column family’s TTL    Any MOB HFile older than a "too recent" threshold with no references to it from the regular hfiles for all regions in a column family     MOB files are cleaned when MOB cleaner chore runs. This runs every 24 hours. Cleaner chore identifies the files whose TTL's are expired and removes them. TTL needs to be set on a table schema level. Default TTL is forever.      hbase.master.mob.cleaner.period   Description  The period that MobFileCleanerChore runs. The unit is second. The default value is one day. The MOB file name uses only the date part of the file creation time in it. We use this time for deciding TTL expiry of the files. So the removal of TTL expired files might be delayed. The max delay might be 24 hrs.    Default  86400  Always verify the answers from AI generated sources before posting it to community.   Reference -  https://hbase.apache.org/book.html#_mob_architecture  cc: @cjervis

							 Hi @allen_chu @Shelton   There is no configuration named hbase.mob.file.expired.period in any of the hbase versions. @Shelton Could you please give reference for the property you have shared?
