Lokesh Jain updated HDFS-12521:
-------------------------------
Attachment: HDFS-12521-HDFS-7240.004.patch
Thanks [~linyiqun] [~anu] for the review. Version 4 patch addresses the
comments by [~anu]. The listContainer json output changes after the patch as
now the function outputs a list of ContainerInfo instead of list of Pipelines.
Therefore the json now contains field from ContainerInfo class as well. I have
added a test for the ignorableFieldNames of Pipeline in
TestSCMCli#testListContainerJson. A separate class can also be created for
testing the json outputs.
