Baiqiang Zhao commented on HBASE-25655: --------------------------------------- Thanks [~anoop.hbase]. Yes, use --size can not hot spot one or few regions for randomRead and randomSeekScan. My example may be a bit special. But what about asyncRandomRead, append, checkAndPut, scanRangeXX etc. > Add a new option in PE to indicate the current number of rows in the test > table > ------------------------------------------------------------------------------- > > Key: HBASE-25655 > URL: https://issues.apache.org/jira/browse/HBASE-25655 > Project: HBase > Issue Type: Improvement > Components: PE > Reporter: Baiqiang Zhao > Assignee: Baiqiang Zhao > Priority: Major > > When we have written 100000 rows in TestTable with 10 preSplits. Then we want > to test randomRead with 10 threads, per thread read 1000 rows. But the range > of all read keys is in [0, 10000], all in the first region. It may cause > hotspot problem, and the result is not accurate. > This issue add a new option "initRows" to solve this problem. -- This message was sent by Atlassian Jira (v8.3.4#803005)
