Hello everyone, We are upgrading our Hadoop/HBase cluster from Hadoop 2.8.5 & HBase 2.2.5 to Hadoop 3.3.6 & HBase 2.5.7
The Hadoop upgrade worked well, but unfortunately we have problems with the Hbase upgrade, because the master hangs on startup inside the „Starting assignment manger“ task. After 15 minutes the following message appears in the log file: Master failed to complete initialization after 900000ms. Please consider submitting a bug report including a thread dump of this process. We face the same problem as Adam a couple of weeks ago: "Rolling upgrade from HBase 2.2.2 to 2.5.8 [typo corrected]: There are 2336 corrupted procedures“ and we fixed it in the same way by deleting the MasterProcWALs-folder in HDFS. I can provide HMaster dump and a dump of one data nodes! How can we proceed with the upgrade? Thanks and best regards Udo
