Haohui Mai commented on HADOOP-10995: ------------------------------------- bq. Actually, the hbase libs only, we will stop the cascading dependency Can you be more specific?

That is said, this will block incompatible changes like HADOOP-10075, HADOOP-10101 going into trunk. That beats the whole point of having the trunk branch. > HBase cannot run correctly with Hadoop trunk > -------------------------------------------- > > Key: HADOOP-10995 > URL: https://issues.apache.org/jira/browse/HADOOP-10995 > Project: Hadoop Common > Issue Type: Bug > Reporter: Zhijie Shen > Assignee: Zhijie Shen > Priority: Critical > Attachments: HADOOP-10995.1.patch > > > Several incompatible changes that happened on trunk but not on branch-2 have > broken the compatibility for HBbase: > HADOOP-10348 > HADOOP-8124 > HADOOP-10255 > In general, HttpServer is and Syncable.sync have been missed. > It blocks YARN-2032, which makes timeline sever support HBase store. -- This message was sent by Atlassian JIRA (v6.2#6252)
