Accumulo team, Our team is upgrading from Accumulo 1.5.4 to 1.6.6 then to 1.7.3. We are testing the upgrade in our integration environment. Before we started the upgrade, we copied our HDFS /accumulo directory to /accumulo_backup. My hope was that I could just swap out the directories to rollback. However when I did, the metadata table didn't load. I looked at the tables and the metadata table was listed as "metadata" versus "!METADATA" indicating it was using the new format of the tables. My guess is that zookeeper is maintaining the previous upgraded table names.
My question is what is the easiest way to rollback the data. Thanks Bob Sent from my Verizon, Samsung Galaxy smartphone
