Stephen Yuan Jiang updated HBASE-13711:
---------------------------------------
Fix Version/s: 1.1.1
> Provide an API to set min and max versions in HColumnDescriptor
> ---------------------------------------------------------------
>
> Key: HBASE-13711
> URL: https://issues.apache.org/jira/browse/HBASE-13711
> Project: HBase
> Issue Type: Bug
> Affects Versions: 2.0.0, 1.1.0, 1.2.0
> Reporter: Stephen Yuan Jiang
> Assignee: Stephen Yuan Jiang
> Priority: Minor
> Fix For: 2.0.0, 0.98.14, 1.2.0, 1.1.1
>
> Attachments: HBASE-13711-v2.patch, HBASE-13711.patch,
> HBASE-13711.v1-branch-1.1.patch

> In org.apache.hadoop.hbase.chaos.actions.ChangeVersionsAction#perform(), it
> tries to update the max and min versions in a column descriptor:
> {code}
> for(HColumnDescriptor descriptor:columnDescriptors) {
> descriptor.setMaxVersions(versions);
> descriptor.setMinVersions(versions);
> }
> {code}
> If the current minimum version is greater than the new max version, an
> IllegalArgumentException would throw from
> org.apache.hadoop.hbase.HColumnDescriptor#setMaxVersions().
> Here is an example (trying to set max version to 1 while currently min
> version is 2):
> {noformat}
> java.lang.IllegalArgumentException: Set MaxVersion to 1 while minVersion is
> 2. Maximum versions must be >= minimum versions
> at
> org.apache.hadoop.hbase.HColumnDescriptor.setMaxVersions(HColumnDescriptor.java:634)
> at
> org.apache.hadoop.hbase.chaos.actions.ChangeVersionsAction.perform(ChangeVersionsAction.java:62)
> {noformat}
> One solution is to change the order of set - set min version first and then
> set max version (note: the current implement of
> org.apache.hadoop.hbase.HColumnDescriptor#setMinVersions() does not check the
> min version value and blindly set the version. Not sure whether this is
> by-design).
> Another solution is to provide an API to set both min and max version in one
> function call.
