Chris Nauroth updated HDFS-4373:
--------------------------------
Attachment: HDFS-4373.2.patch
Thanks, Jing. Here is version 2 of the patch.
{quote}
Based on the current changes in HDFS-4372, StartupProgressServlet#putIfNotNull
may need to be updated since we no longer use Long and null for regular and
uninitialized fields of Step.
{quote}
This has been changed so that it only handles nullable {{String}} values, and
there is just one remaining special case in the main method to check for
{{Long#MIN_VALUE}} on the optional size.
{quote}
In StartupProgressServlet, instead of putting all the information contained in
a StartupProgressView into a newly-created map and converting the map into
Json, can we directly dump the StartupProgressView instance into the response's
writer using Json (just like Configuration#dumpConfiguration)?
{quote}
Yes, I've rewritten this code to use the Jackson streaming API.
{quote}
We can clean the imports in both TestStartupProgressServlet.java and
StartupProgressServlet.java
{quote}
This is done.
