Hitesh Shah commented on TEZ-14:
--------------------------------
Comments:
{code}
+ private boolean isSpeculationEnabled() {
+ return conf.getBoolean(TezConfiguration.TEZ_AM_SPECULATION_ENABLED,
+ TezConfiguration.TEZ_AM_SPECULATION_ENABLED_DEFAULT);
+ }
{code}
- for ta.isSpeculationEnabled(), switch to a class member var?
- TaskAttempStatusUpdateEventTransition indentation for a brace is a bit off
- private static final long MAX_WAITTING_TIME_FOR_HEARTBEAT = 9 * 1000; - this
might be problematic where the heartbeat value is wildly different.
- spurious change in
tez-mapreduce/src/main/java/org/apache/tez/mapreduce/hadoop/MRJobConfig.java
More comments pending.
