[jira] [Commented] (BIGTOP-12) Add HCatalog to Bigtop
[ https://issues.apache.org/jira/browse/BIGTOP-12?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13205797#comment-13205797 ]
Bruno Mahé commented on BIGTOP-12:
----------------------------------
Great start! Thank you very much for taking care of this ticket.
I know this is a work in progress but some notes:
* I see a lot of references to hive even in files where occurrences have been replaced (see @HIVE_DAEMON@ in bigtop-packages/src/common/hcatalog/hcat_server.sh for instance)
* typo: +HIVE_USER="hcatalgo"
* I don't see the python parameter being used in the install script
* in bigtop-packages/src/deb/hcatalog/hcatalog.postinst, no need to create the warehouse manually. There is now a script to do that. But we should not do these calls at configure time anyway. We cannot assume there is a hadoop cluster running and in some cases, may even create a /user/hive/warehouse on local filesystem. The metastore rename can also be removed since there is no upgrade from any previous version (but I guess this is a left over the original hive files used as a template)
* No need for the "+Obsoletes: %{name}-webinterface" in the spec file
* No need to require hadoop >= 0.20.2 in the spec file since Apache bigtop has never provided a version less than 0.20.2
* I see hcatalog providing a hive binary. Is this on purpose or a work in progress? IF so, it should conflicts with hive package
* In the install script, I see you are moving hcat binary to /usr/bin/. How does that work regarding JAVA_HOME? Is there any need to write a wrapper script to source hcatalog default file and bigtop-utils' java home autodetection script?
Again, thank you very much!
