trunk/ql/src/java/org/apache/hadoop/hive/ql/MapRedStats.java <https://reviews.apache.org/r/2167/#comment5396> remove the enum, just either put all the counters objects into this MapRedStats, or put a map<counterGrpAndName, counterInst> here. For simplicity, we can just put the counters object here and hooks can anything they want. - Yongqiang On 2011-10-04 22:58:24, Kevin Wilfong wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
