Re: Maven build: YARN timeline service downloading maven-metadata from personal repository?

[Li Lu]

Let’s remove the Phoenix dependency if that’s blocking builds now. The offline 
aggregator can be added later.

However, there is PhoenixOfflineAggregationWriterImpl.java which does import

If everybody is cool to remove that for now, then we can deal with Phoenix as 
and when we're ready to add the offline aggregation.

Re: [DISCUSS] Set minimum version of Hadoop 3 to JDK8 (HADOOP-11858)

I’d like to bring YARN-4977 into attention for using Java 8. HADOOP-13083 does 
the maven change and in yarn-api there are ~5000 javadoc warnings.

   — YARN Timeline Service v1.5 - YARN-4233: A short term bridge before 
YARN-2928 comes around. I think this should go in given the tremendous activity 
recently.

+1, let’s target ATS v1.5 work to 2.8. Most critical patches will be ready for 
review this week. YARN-4234 also addresses the versioning problem for ATS v1, 
v1.5, and v2, which will bridge the gap between v1 and v2.

   — YARN Timeline Service Next generation: YARN-2928: Lots of momentum, but 
clearly a work in progress. Two options here
   — If it is safe to ship it into 2.8 in a disable manner, we can get the 
early code into trunk and all the way int o2.8.

Let’s review all changes in YARN-2928 branch and evaluate their impact on the 
upstream code. Right now in YARN-2928 branch we’ve modified RM/NM/Distributed 
shell and MR. Before we make a decision on this I think we need to review their 
effects so that ATS v2 (in its alpha mode) is not affecting existing parts.

   — If it is not safe, it organically rolls over into 2.9

Sure.

RetryUpToMaximumTimeWithFixedSleep now inherits 
RetryUpToMaximumCountWithFixedSleep and just acts as a wrapper to decide 
maxRetries. The current implementation uses (maxTime / sleepTime) as the number 
of maxRetries. This is fine if the actual for each retry is significantly less 
than the sleep time, but it becomes less accurate if each retry takes 
comparable amount of time as the sleep time. The problem gets worse when there 
are underlying retries. 

We may want to use timers inside RetryUpToMaximumTimeWithFixedSleep to perform 
accurate timing.

 Summary: Remove hadoop.util.PriorityQueue
 Key: HADOOP-11304
 URL: https://issues.apache.org/jira/browse/HADOOP-11304

  Issue Type: Bug
  Components: util
Reporter: Li Lu

PriorityQueue is supported from Java 5 on, but we're mixing the use of the Java 
PriorityQueue with hadoop's own PriorityQueue. We may want to make this 
consistent and only use the Java one.
