Figured this out internally . Turns out the spark optimization routine can be affected by the configuration setting spark.sql.codegen.Maxfields which can have implications in how spark will optimize the read from 'fat' tables . In my case the setting was set low which means DAG stages of the read from the right side of the join (the "fat" table) were performed without being assigned to a wholestage codegen . Important to note that the read of the hive data in either case returned the same results just with a different optimization applied to the physical plan .

Hi community I am trying to debug a simple query in spark SQL that is returning incorrect data. In this instance the query is a simple join between two hive tables .. The issue seems tied to the fact that a the physical plan that spark has generated (with catalyst optimization) looks to be corrupted where some of the steps in the physical plan have not been assigned an evaluation order id and thus all evaluation on the right side of the join is not completed in the spark query This error is on a HDP3.1.4 cluster running >>> sc.version
u'2.3.2.3.1.4.0-315' here is the example query .. from pyspark_llap import HiveWarehouseSession
hive = HiveWarehouseSession.session(spark).build()
filter_1 = hive.executeQuery('select * from 03_score where scores = 5 or scores = 6')
filter_2 = hive.executeQuery('select * from 03_score where scores = 8')
joined_df = filter_1.alias('o').join(filter_2.alias('po'), filter_1.encntr_id == filter_2.encntr_id, how='inner')
joined_df.count() ### shows incorrect value ###
joined_df.explain(True) and here is the output of plan evaluation == Physical Plan ==
SortMergeJoin [encntr_id#0], [encntr_id#12], Inner
:- *(2) Sort [encntr_id#0 ASC NULLS FIRST], false, 0
: +- Exchange hashpartitioning(encntr_id#0, 200)
: +- *(1) Filter isnotnull(encntr_id#0)
: +- *(1) DataSourceV2Scan [encntr_id#0, scores_datetime#1, scores#2], com.hortonworks.spark.sql.hive.llap.HiveWarehouseDataSourceReader@a6df563
+- Sort [encntr_id#12 ASC NULLS FIRST], false, 0
+- Exchange hashpartitioning(encntr_id#12, 200)
+- Filter isnotnull(encntr_id#12)

Can anyone shed some light on this issue for me .. Why would the physical plan which looks correct not be assigned an evaluation order id ?

I have the following issue with this setup . .I define Livy service on a Knox topology with authentication provider enabled . When I request the Livy session over Knox url Knox requests the Livy session with doAs = myuser . So far so good. .. Livy sessions is started with owner=Knox and proxyuser =myuser.. Problem is when we attempt to post to Livy statements API over the Knox url. If we use the Knox url for posting to the running Livy session Knox will add the doAs=myuser . But now we get a forbidden response . Basically because the Livy session is owned by Knox we cannot post statement into the session over the Knox url with doAs=myuser . in my setup at least only the Knox user may post a statement to a Livy session owned by Knox .

With the Advent of heterogeneous storage for hdfs can we now look at Nas in a new light .. Potentially we could lable Nas mounts on a data nodes as archive storage and have hdfs move data in there when it becomes cold I would like to hear opinions on this

Hi All.
We have an issue with cloudera navigator UI on 6.2 manual installation .. Background..
Installed the navigator audit and metadat server roles on a cluster backed by external postgresql database
CDH is using auto_TLS
Navigator metadata and audit roles are status green on the cloudera manager UI
However when i browse to the navigator UI we get a status 503 service unavailable message.
we have confirmed the navigator role is up and running
[root@cmhdgateway01 hue]# lsof -i:7187 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME java 12766 cloudera-scm 532u IPv4 814278 0t0 TCP *:7187 (LISTEN) python2.7 17534 hue 31u IPv4 955050 0t0 TCP cmhdgateway01.cso.ie:50144->cmhdgateway01.cso.ie:7187 (CLOSE_WAIT) [root@cmhdgateway01 hue]#
