Subject [jira] [Commented] (AMBARI-2118) ambari-web modifications to allow for Hadoop Compatible Filesystems (HCFS)
Date Fri, 31 May 2013 00:43:20 GMT


Yusaku Sako commented on AMBARI-2118:

Hello [~croberts], here's my feedback so far.  Sorry for the delay:

* /app/assets/data/wizard/deploy/5_hosts/poll_6.json: Please don't include the changes to
this file, as this is used for testing scenarios where the server returns a response for the
start API.  It might be a good idea to introduce another set of mock data for which the step
for start API is empty.

* /app/controllers/wizard/step8_controller.js: 
+       case 'HCFS':
+         return {config: {'global': 'version1', 'core-site': 'version1'}};   
The above does not apply because getConfigForService function has been removed (this function
is no longer used).

* /app/controllers/wizard/step9_controller.js: This needs further review.  This step needs
to handle various edge cases (retry upon installation failure, page refreshes, etc).  

* /app/data/config_mapping.js: definition is duplicated.  We should remove
the redundant entry and manage the value in code (e.g., hdfs://namenode_host:8020 for HDFS
and whatever is appropriate for glusterfs).

* /app/data/config_properties.js: the newly added glusterfs properties have the "filename"
attribute.  These should be removed.

* /app/data/service_configs.js: For the newly added HCFS object, "configs" should be an empty
array, and "sites" should be added (see others)

* /app/config.js: Skip this file from the patch

* /app/messages/js: installer.step4.multileDFS.popup.header and installer.step4.multileDFS.popup.body
are misspelled.

> Make modifications to ambari-web that will allow for the selection of a Hadoop Compatible
Filesystem.  These changes include allowing HDFS to be unselected (either HDFS or HCFS must
be selected).  If HCFS is chosen, push appropriate configuration (site-conf.xml) files during
the install so that systems will work with HCFS as the underlying filesystem rather than HDFS.
