Hi @steven-matison The issue got fixed after making below 2 changes in /etc/krb5.conf file   1. Issue was a include line in my /etc/krb5.conf file which was not valid. Removed below from /etc/krb5.conf "includedir /etc/krb5.conf.d/"   2. On macOS the default client does not fall back to TCP. In krb5.conf prefix kdc value with tcp/ to force the client to use TCP if your corporate network blocks UDP. kdc = tcp/kdc.example.com:88   Regards, Banshi. ... View more

Hi @steven-matison You are right. I have replaced actual REALM with EXAMPLE.COM while posting.    I have checked connectivity using "nc -zv" and "ping" command. Connectivity is fine. ==== nc -zv <kdc_server_VIP> <KDC_Port> Connection to xxxxxxxx port xxxxxx [tcp/sqlexec] succeeded! ==== --- <kdc_server_VIP> ping statistics --- 13 packets transmitted, 12 packets received, 7.7% packet loss ====   "kinit: krb5_get_init_creds: unable to reach any KDC in realm EXAMPLE.COM, tried 0 KDCs" By seeing the above error, I feel it's not able to locate the krb5.conf file.   When we run kinit command, is it referring to /etc directory for krb5.conf file or some other location in Mac machine?   Regards, Banshi.       ...

Hi @GangWar,   As per CDH package information, Impala 3.2 comes with CDH 6.3.x. Not with CDH 5. Refer below details.   ====== CDH 5.x comes with Impala 2.x. https://docs.cloudera.com/documentation/enterprise/release-notes/topics/cdh_vd_cdh_package_tarball_515.html#cm_vd_cdh_package_tarball_515   CDH 6.3.x comes with Impala 3.2.  https://docs.cloudera.com/documentation/enterprise/6/release-notes/topics/rg_cdh_63_packaging.html#concept_rtm_b5p_m3b ======   Can you elaborate how to upgrade impala from 2.11 to 3.2 in CDH 5.14.   Regards, Banshi. ...

Hi @bgooley ,   Thank you for your suggestion. We set the same property and it fixed the issue.   Cloudera Manager --> YARN --> searched for: Gateway Client Environment Advanced Configuration Snippet (Safety Valve) for hadoop-env.sh and added this:   HADOOP_CLIENT_OPTS="-Djava.io.tmpdir=/ngs/app/$(whoami)/hadoop/tmp"   Regards, Banshi. ...

Hi Team,   We are facing an issue where mapreduce jobs are failing with below error. Distribution: Cloudera (CDH 5.14.4)   ==== Exception in thread "main" java.io.FileNotFoundException: /tmp/hadoop-unjar5272208588996002870/org/apache/hadoop/hive/metastore/api/ThriftHiveMetastore$AsyncClient$revoke_privileges_call.class (No space left on device)         at java.io.FileOutputStream.open0(Native Method)         at java.io.FileOutputStream.open(FileOutputStream.java:270)         at java.io.FileOutputStream.<init>(FileOutputStream.java:213)         at java.io.FileOutputStream.<init>(FileOutputStream.java:162)         at org.apache.hadoop.util.RunJar.unJar(RunJar.java:110)         at org.apache.hadoop.util.RunJar.unJar(RunJar.java:81)         at org.apache.hadoop.util.RunJar.run(RunJar.java:214)         at org.apache.hadoop.util.RunJar.main(RunJar.java:141) ====   We figured out that MR framework tries to keep temporary class files under /tmp dir with a folder named hadoop-unjarxxxxxx. As there is not enough space in /tmp to hold the class files, it fails with above error.   We want to change the default location for hadoop-unjarxxxxxx directory. We changed the default value of hadoop.tmp.dir in core-site.xml (safety valve) to /ngs/app/${user.name}/hadoop/tmp , but it’s of no help.   Any suggestion on how to change the default hadoop-unjar location from /tmp to something else.   Regards, Banshi. ...
