Schedule all log-spliiting at startup all at once
-------------------------------------------------
Key: HBASE-3963
URL: https://issues.apache.org/jira/browse/HBASE-3963
Project: HBase
Issue Type: Improvement
Reporter: Prakash Khemani
Assignee: Prakash Khemani
When distributed log splitting is enabled then it is better to call splitLog()
for all region servers simultaneously. A large number of splitlog tasks will
get scheduled - one for each log file. But a splitlog-worker (region server)
executes only one task at a time and there shouldn't be a danger of DFS
overload. Scheduling all the tasks at once ensures maximum parallelism.
