Subject [jira] [Commented] (HBASE-8816) Add support of loading multiple tables into LoadTestTool
Date Thu, 11 Jul 2013 22:17:49 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8816?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13706333#comment-13706333

Enis Soztutar commented on HBASE-8816:
--------------------------------------

bq. How about passing a comma-separated list of table names to the -tn parameter?
Sounds good, but if you want to run with 50 tables, 10 writer/readers each, then passing that
parameter will become ugly, no?

> Introducing an optional parameter 'concurrent_factor' into LoadTestTool. When it's specified
with positive integer n, LoadTestTool will load n tables parallely. -tn parameter value becomes
table name prefix. Tables are created with name in format <tn>_1...<tn>_n. A sample
command line "-tn test -concurrent_factor 2" will create & load tables:"test_1" and "test_2"
> The motivation is to add a handy way to load multiple tables concurrently. In addition,
we could use this option to test resource leakage of long running clients.
