Re: Unable to see completed application in Spark 2 history web UI
Thanks Manu for your response. I already checked the logs and didn't see anything that can help me understanding the issue. The more weird thing, i have a small CI cluster which run on single NameNode and i see the Spark2 job in the UI, i'm still not sure if it may related to the NameNode HA, i tried to replace the logdir from NameNode HA to the activeNameNode like this http://server:8020/user/spark/spark2historyapplication in the spark2 default conf but the UI still showing the the path with the HA NameNode event after a restart of Spark2. The issue become more intersting :) On Fri, Aug 17, 2018 at 2:01 AM Manu Zhang wrote: > Hi Fawze, > > Sorry but I'm not familiar with CM.

Hi Fawze, Sorry but I'm not familiar with CM. Maybe you can look into the logs (or turn on DEBUG log).

Re: Unable to see completed application in Spark 2 history web UI
Hi Manu, I'm using cloudera manager with single user mode and every process is running with cloudera-scm user, the cloudera-scm is a super user and this is why i was confused how it worked in spark 1.6 and not in spark 2.3 On Thu, Aug 16, 2018 at 5:34 AM Manu Zhang wrote: > If you are able to log onto the node where UI has been launched, then try > `ps -aux | grep HistoryServer` and the first column of output should be the > user. > > On Wed, Aug 15, 2018 at 10:26 PM Fawze Abujaber wrote: > >> Thanks Manu, Do you know how i can see which user the UI is running, >> because i'm using cloudera manager and i created a user for cloudera >> manager and called it spark but this didn't solve me issue and here i'm >> trying to find out the user for the spark hisotry UI. >> >> On Wed, Aug 15, 2018 at 5:11 PM Manu Zhang >> wrote: >> >>> Hi Fawze, >>> >>> A) The file permission is currently hard coded to 770 ( >>> https://github.com/apache/spark/blob/branch-2.3/core/src/main/scala/org/apache/spark/scheduler/EventLoggingListener.scala#L287 >>> ). >>> B) I think add all users (including UI) to the group like Spark will do. >>> >>> >>> On Wed, Aug 15, 2018 at 6:38 PM Fawze Abujaber >>> wrote: >>> Hi Manu, Thanks for your response.

Re: Unable to see completed application in Spark 2 history web UI
If you are able to log onto the node where UI has been launched, then try `ps -aux | grep HistoryServer` and the first column of output should be the user.

Re: Unable to see completed application in Spark 2 history web UI
Thanks Manu, Do you know how i can see which user the UI is running, because i'm using cloudera manager and i created a user for cloudera manager and called it spark but this didn't solve me issue and here i'm trying to find out the user for the spark hisotry UI.

Re: Unable to see completed application in Spark 2 history web UI
Hi Fawze, A) The file permission is currently hard coded to 770 ( https://github.com/apache/spark/blob/branch-2.3/core/src/main/scala/org/apache/spark/scheduler/EventLoggingListener.scala#L287 ). B) I think add all users (including UI) to the group like Spark will do.

Re: Unable to see completed application in Spark 2 history web UI
Hi Manu, Thanks for your response. Yes, i see but still interesting to know how i can see these applications from the spark history UI. How i can know with which user i'm logged in when i'm navigating the spark history UI. The Spark process is running with cloudera-scm and the events written in the spark2history folder at the HDFS written with the user name who is running the application and group spark (770 permissions). I'm interesting to see if i can force these logs to be written with 774 or 775 permission or finding another solutions that enable Rnd or anyone to be able to investigate his application logs using the UI. for example : can i use such spark conf : spark.eventLog.permissions=755 The 2 options i see here: A) find a way to enforce these logs to be written with other permissions. B) Find the user that the UI running with as creating LDAP groups and user that can handle this. for example creating group called Spark and create the user that the UI running with and add this user to the spark group. not sure if this option will work as i don't know if these steps authenticate against the LDAP.
Re: Unable to see completed application in Spark 2 history web UI
Hi Fawze, In Spark 2.3, HistoryServer will check for file permissions when reading event logs written by your applications. (Please check https://issues.apache.org/jira/browse/SPARK-20172). With file permissions of 770, HistoryServer is not permitted to read the event log. That's why you were able to see applications once changing file permissions to 777.

Unable to see completed application in Spark 2 history web UI
Hello Community, I'm using Spark 2.3 and Spark 1.6.0 in my cluster with Cloudera distribution 5.13.0. Both are configured to run on Yarn, but i'm unable to see completed application in Spark2 history server, while in Spark 1.6.0 i did. 1) I checked the HDFS permissions for both folders and both have the same permissions. drwxrwxrwt - cloudera-scm spark 0 2018-08-08 00:46 /user/spark/applicationHistory drwxrwxrwt - cloudera-scm spark 0 2018-08-08 00:46 /user/spark/spark2ApplicationHistory The applications file itself running with permissions 770 in both. -rwxrwx--- 3 fawzea spark 4743751 2018-08-07 23:32 /user/spark/spark2ApplicationHistory/application_1527404701551_672816_1 -rwxrwx--- 3 fawzea spark 134315 2018-08-08 00:41 /user/spark/applicationHistory/application_1527404701551_673359_1 2) No error in the Spark2 history server log. 3) Compared the configurations between Spark 1.6 and Spark 2.3 like system user, enable log, etc ... all looks the same. 4) Once i changed the permissions for the above Spark2 applications to 777, i was able to see the application in the spark2 history server UI. Tried to figure out if the 2 Sparks UIs running with different users but was unable to find it. Anyone who ran into this issue and solved it? Thanks in advance. -- Take Care Fawze Abujaber
