This might help to other people. This seems like a bug : https://issues.apache.org/jira/browse/AMBARI-21687 The bug is fixed in 2.6.0.0 branch only ( not fixed in 2.4.x.x or 2.5.x.x versions of ambari). So, The available workaround is to add the node via 'Admin' user or use the ambari 2.6.x ... View more

You can try adding this "hadoop.ssl.enabled.protocols" property in custom core-site in ambari->HDFS service. See [1] for information on this property : [1] https://hadoop.apache.org/docs/r2.7.2/hadoop-project-dist/hadoop-common/core-default.xml ... View more

Yes, that's correct. Hortonworks does not support the fair scheduler and it's not suggested to use this in production. See [1] [1] https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.3/bk_release-notes/content/community_features.html ... View more

Binary Type vs String type in ORC table

by Explorer pdegave in Support Questions
‎11-13-2017 09:55 AM
‎11-13-2017 09:55 AM
In what scenario we have to choose the binary type or string type in ORC table? It my understanding that, we have to use the type as binary when the datatype string value is more than > 2Gb and If it's below than 2GB then we can go for string data type. Is that correct? I've already seen this : https://orc.apache.org/docs/encodings.html When we use string type value less than 2GB, getting below error but when switched to binary it's working as expected. Any idea what could be the cause.

@Sara Alizadeh Did you mean after enabling maintenance mode on namenode, you can not edit the config changes from ambari ? Please note Without enabling maintenance mode you can change the java heap size. Please see article [1] which talks on how to set namenode heap size. Also, see thread [2] which also talks on same.
