[jira] [Commented] (HBASE-7936) Undo prefix-tree module as dependency for mapreduce and for DataBlockEncoding

    [ https://issues.apache.org/jira/browse/HBASE-7936?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13590291#comment-13590291 ] 

Ted Yu commented on HBASE-7936:
-------------------------------

A similar approach is to introduce third parameter to DataBlockEncoding ctor, signifying whether encoder should be lazily loaded.
Since only PrefixTreeCodec lives in its own module at the moment, we can pass true for PrefixTreeCodec and pass false to the other encoders.

> Fix DBE so it does lazy loading rather than hard loading of everything mentioned.
> Client depends on prefix-tree module since HBASE-7188 and mapreduce will after hbase-7934
