You are a SAVIOUR !! I made a script to assign all regions with ""not deployed on any region server"" and now it works fine!! Awesome thanks a lot mate!

Hi RKI, the command worked, that error now is gone... but doing "hbase hbck -details" i goit 560 inconsistencies all equals: ERROR: There is a hole in the region chain between and . You need to create a new .regioninfo and region dir in hdfs to plug the hole.

Hi @rki_and thanks for your answer, was exaclty was needed. But, if i may ask, after that i see all regions server online, 0 offline and all regions on 1 region server execept for meta that is on another one (in total i have 3). The problem is that i got this error in master: org.apache.hadoop.hbase.NotServingRegionException: hbase:quota,,1620896369946.28dd7c81713c9347e8dfe4e6993b1ec7. is not online on my-server3.domain.com,16020,1658432084980 Do you have any idea on what could i do? Thanks

Hello everybody, basically there was an electric problem and the cluster was suddently shutdown. After restarting everything Hbase results to have all the Region Servers online (but with 0 regions each) and the Region Server with the same names are shown in Dead Region Servers. Everytime i restart hbase, new rows are add in the Dead Region Server . This already happened to me long time ago and the problem was related to zookeeper, but i can't find the old post. Do you know what i can do? Thanks P.S. my cluster is kerberized, hbase version 2.0

As described in the link that i posted above, those steps works perfectly: P.S. i stopped ambari-server before doing those $ grep "password" /etc/ambari-server/conf/ambari.properties server.jdbc.user.passwd=/etc/ambari-server/conf/password.dat $ echo "bigdata_custom" > /etc/ambari-server/conf/password.dat $ sudo -u postgres psql postgres=# ALTER USER ambari WITH PASSWORD 'bigdata_custom'; postgres=# \q $ ambari-server restart

Hi all, i saw this guide: https://community.cloudera.com/t5/Support-Questions/how-to-change-password-for-ambari-db-post-install/td-p/126685 but it was for Ambari 2.2.0 and i was wondering if do you think is the same for Ambari 2.7.4. I have in ambari.properties: - server.jdbc.user.passwd=/etc/ambari-server/conf/password.dat Doing "cat /etc/ambari-server/conf/password.dat " i see the default password (bigdata) in plain, so NO PASSWORD ENCRYPTION ENABLED. I'm using Postgres 9.3 Thanks!!

I tried to set yarn.scheduler.capacity.maximum-am-resource-percent to 1 but doesnt changed a bit. I added from Ambari under custom yarn-site.

It's reported as "INFO", but then it doesnt submit the app on Yarn, remain stuck. INFO: 22/01/27 12:38:44 INFO Client: Verifying our application has not requested more than the maximum memory capability of the cluster (3072 MB per container), INFO: Exception in thread "main" java.lang.IllegalArgumentException: Required AM memory (5214+521 MB) is above the max threshold (3072 MB) of this cluster! Please increase the value of 'yarn.scheduler.maximum-allocation-mb'.

Hi, thanks for the tip i checked but everything seems ok: <property> <name>yarn.scheduler.maximum-allocation-mb</name> <value>15360</value> </property> I upgraded some minutes ago at 15360 MB and in fact it's there. But still i keep get that error. Yarn it's all good, no error no warning nothing.

loridigia · ‎01-27-2022

Hi, since i'm in Cluster Mode i set spark.driver.memory = 6G And it doesnt work since keep saying that maximum is 3072MB. I tried on another cluster and actually changing yarn.nodemanager.resource.memory-mb and yarn.scheduler.maximum-allocation-mb to a lower value than spark.driver.memory i obtain the same error as above. So at this point i guess that Yarn (on my cluster) doesn't update the parameters values. I updated them from AMBARI and try to restart YARN many times but nothing changed.
