Subject [jira] [Commented] (HADOOP-10366) [Doc] wrap value of io.serializations in core-default.xml to fit better in browser
Date Sun, 17 May 2015 01:43:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10366?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14547011#comment-14547011

Akira AJISAKA commented on HADOOP-10366:

Hi [~kanaka], thank you for taking this issue.
I don't think it's a good idea to render the value in the fixed number of characters. Users
may copy and paste the parameter, which is rendered in the middle of the classes, from browser.
As the result, application can fail.
I'm thinking it makes more sense to add a whitespace between the classes as follows:
<value>org.apache.hadoop.io.serializer.WritableSerialization, org.apache.hadoop.io.serializer.avro.AvroSpecificSerialization,
That way we can fix the problem. When the value is read from o.a.h.io.serializer.SerializationFactory,
the whitespaces are trimmed.

Due to this single very long line, the "description" column can not show in browser by default
