UNOFFICIAL Hi, I have a custom table balancer set on a particular table, and a cron job that creates splits for the next-days data, each day. Normally it is all fine, but after some problems happened, I found that for certain days all the splits resided on a single tablet server - which then caused performance problems with ingest. This was solved by temporarily taking the tablet server out of the cluster (stopping the Accumulo service not HDFS) and then (days) later putting it back. This caused a re-assignment of the tablets and presumably triggered the table balancer as part of that. This seemed like a very heavy-handed solution and brought about the question:
What is the recommended (least intrusive) way to trigger the table balancer in Accumulo for a known set of splits (tablets)? Additional information: whilst the cluster is well balanced in terms of tablets-per-server, there is an imbalance in terms of entries (3-1 or 5-1 in some cases). I noticed that the new (empty) pre-splits appeared to be on the server or servers with significantly less entries. Thank you in advance. Bruce.
