Hi I have run into an issue several times now and could really use some help diagnosing the problem.
Environment:phoenix 4.4hbase 0.9834 node clusterTables are defined with 40 salt bucketsWe are continuously loading large, bz2, csv files into Phoenix via Pig.The data is in the hundred of TB’s per month
The process runs well for a few weeks but as the regions split and the number of regions gets into the hundreds per table we begin to get “RegionTooBusy” exceptions around Phoenix write code when the Pig jobs run.
Something else I have noticed is the number of requests on the regions becomes really unbalanced. While the number of regions is around 40, 80, 120 the number of requests per region (via the hbase master site) is pretty well balanced. But as the number gets into the 200’s many of the regions have 0 requests while the other regions have hundreds of millions of requests.
If I drop the tables and start over the issue goes away. But we are approaching a production deadline and this is no longer an option.
The cluster is on a closed network so sending log files is not possible although I can send scanned images of logs and answer specific questions.
Can you please help me diagnose this issue.
