[jira] Commented: (HADOOP-414) replace class UTF8 with class Text

    [ https://issues.apache.org/jira/browse/HADOOP-414?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12504056 ] 

stack commented on HADOOP-414:
------------------------------

Added a vote to this issue.  HBase spends a bunch of time rpc'ing.  A loads of our time is spent in UTF8 class doing reading and writing on the wire.  A primitive test has the Text.readString/writeString being a good bit faster than the UTF8 equivs so would be great if RPC moved to off UTF8 and on to Text.

> Since class UTF8 is deprecated, all references of UTF8 in hadoop should be replaced with class Text if the change does not break the system.
