Sean Busbey commented on HBASE-11627: ------------------------------------- [~louis.hust], if there's also an error in the calculation of splitCount it's probably best to open that as a new ticket. A good indicator that it isn't directly related to the divide by zero is that if I apply your v3 patch and then run the test from my v2 patch (without the guard change) then the test still fails. > RegionSplitter's rollingSplit terminated with "/ by zero", and the > _balancedSplit file was not deleted properly > --------------------------------------------------------------------------------------------------------------- > > Key: HBASE-11627 > URL: https://issues.apache.org/jira/browse/HBASE-11627 > Project: HBase > Issue Type: Bug > Components: Admin, util > Affects Versions: 0.96.2, 0.98.1 > Environment: CentOS release 6.4 (Final) x86_64 && > hbase-0.98.1-cdh5.1.0 > Reporter: louis hust > Priority: Critical > Labels: newbie > Fix For: 0.96.2, 0.98.1 > > Attachments: HBASE_11627-v2.patch, HBASE_11627-v3.patch, > HBASE_11627.patch > > Original Estimate: 24h > Remaining Estimate: 24h > > First create a table > {quote} > > create 't1', 'f1' > {quote} > Then split the table with util: > {quote} > > bin/hbase org.apache.hadoop.hbase.util.RegionSplitter -r -o 2 t1 > > UniformSplit > {quote} > *Finally get the following error :* > {quote} > 12/11/08 19:21:12 DEBUG util.RegionSplitter: All regions have been > successfully split! > 12/11/08 19:21:12 DEBUG util.RegionSplitter: TOTAL TIME = 30sec > 12/11/08 19:21:12 DEBUG util.RegionSplitter: Splits = 0 > Exception in thread "main" java.lang.ArithmeticException: / by zero > at > org.apache.hadoop.hbase.util.RegionSplitter.rollingSplit(RegionSplitter.java:576) > at > org.apache.hadoop.hbase.util.RegionSplitter.main(RegionSplitter.java:349) > {quote} -- This message was sent by Atlassian JIRA (v6.2#6252)
