Rohini Palaniswamy commented on PIG-4714:
-----------------------------------------
bq. With the checking of YarnConfiguration.TIMELINE_SERVICE_ENABLED first, can
we turn on ATS by default
Yes.
{code}
if (Boolean.parseBoolean(pigContext.getProperties()
+ .getProperty(PigConfiguration.ENABLE_ATS))) {
+ if (!Boolean.parseBoolean(pigContext.getProperties()
+
.getProperty("yarn.timeline-service.generic-application-history.enabled"))) {
{code}
should be
{code}
if (Boolean.parseBoolean(pigContext.getProperties()
+ .getProperty(PigConfiguration.ENABLE_ATS, "true"))) {
+ if (!Boolean.parseBoolean(pigContext.getProperties()
+ .getProperty("yarn.timeline-service.enabled", "false"))) {
{code}
ie. Add defaults in case it is null and yarn.timeline-service.enabled instead
of yarn.timeline-service.generic-application-history.enabled. Also the whole
code including setting hdfs context should be within the second if block of
timeline server check.

> The idea is to add callerId to every component, so we can track the chain of
> application which cause the underlining operation. A typical chain is
> Oozie->Pig->Tez->Hdfs. With proper callerId logging, we can trace Hdfs
> operation back to Oozie workflow which triggers it.
> The protocol we decided is every component log its immediate callerId.
> For Pig, this includes passing Pig script ID to underlining components as
> callerId using component specific API, log callerId of Pig and store it on
> ATS. More specific, it includes:
> 1. Generate a CallerId for each Pig script, pass it to
> Hdfs/Yarn/MapReduce/Tez which Pig invokes
> 2. Pig caller passes "pig.log.trace.id" to Pig, Pig will publish it to ATS
