Thanks Jonathan Hurley. Actually this was done by taking reference from similar code from Ambari.(https://github.com/apache/ambari/commit/63f8d74f806aa55fcbb4e51b2c84a3fd0146c062#diff-a9a4cbc8111690ebc76b1e83491d2dba) @Jayush Luniya, can we use version in NORMAL COMMANDS/UPGRADE/DOWNGRADE scenarios? > On July 13, 2016, 2:33 p.m., Jonathan Hurley wrote: > > ambari-server/src/main/resources/common-services/HBASE/0.96.0.2.0/package/scripts/params_linux.py, > > line 60 > > <https://reviews.apache.org/r/49987/diff/1/?file=1443235#file1443235line60> > > > > No need for `stack_version_formatted and` here ... just call > > `check_stack_feature` directly. @Jonathan Hurley, am directly using check_stack_feature here because even if we pass version as ---> 2.3.4.0-1234, the code has format flag as true, which calls format_stack_version() function which can be used for comparision. "compare_versions(stack_version, min_version, format = True) < 0" Also I have added the check for "version" in this way "if upgrade_direction == Direction.DOWNGRADE and version" > On July 13, 2016, 2:33 p.m., Jonathan Hurley wrote: > > ambari-server/src/main/resources/common-services/HDFS/2.1.0.2.0/package/scripts/params_linux.py, > > line 61 > > <https://reviews.apache.org/r/49987/diff/1/?file=1443236#file1443236line61> > > > > No need for `stack_version_formatted and` here ... just call > > `check_stack_feature` directly.
