Carl Steinbach commented on HIVE-2106:
--------------------------------------
trunk/ql/src/java/org/apache/hadoop/hive/ql/exec/Operator.java
<https://reviews.apache.org/r/579/#comment807>
Is this comment still accurate? If so, can we remove this entirely since we
no longer support 0.17?
> Increase the number of operator counter

> Currently Hadoop counters have to be defined as enum (hardcoded) and we
> support up to 400 counters now. This limit the number of operators to 100
> (each operator has 4 counters). We need to increase the hadoop counters or
> change the Hive code to use Hadoop 0.20 API.
