Subject [jira] [Updated] (HBASE-10591) Sanity check table configuration in createTable
Date Tue, 25 Feb 2014 01:13:25 GMT

     [ https://issues.apache.org/jira/browse/HBASE-10591?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Enis Soztutar updated HBASE-10591:
----------------------------------

    Release Note: Introduces sanity checks for table configuration in create and modify table
against some default values. Especially we enforce region split size >= 2MB, memstore flush
size >= 1MB, and 1024 <= block size <= 16MB. If you want to bypass the sanity checks,
you can set "hbase.table.sanity.checks" to false, at global configuration, or at table descriptors
configuration.   (was: Introduces sanity checks for table configuration in create and modify

> We had a cluster completely become unoperational, because a couple of table was erroneously
created with MAX_FILESIZE set to 4K, which resulted in 180K regions in a short interval, and
bringing the master down due to  HBASE-4246.
> We can do some sanity checking in master.createTable() and reject the requests. We already
check the compression there, so it seems a good place. Alter table should also check for this
as well.
