Is there a list of available metrics in Ambari Metrics ?

Thank You @avijayan. This will be really handy going forward.

@Jesse Passwaters @Takahiko Saito Please take a look at https://documentation.altiscale.com/using-csv-serde-with-hive It has example of how to use a different escape character.

Try these additional things. Create a jaas file with following configuration. And launch your java program with these additional options. Client { com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true useTicketCache=false renewTicket=true }; -Djava.security.auth.login.config="path-to-jaas-file" -Djava.security.krb5.conf="path-to-krb5.conf"

@Rachna Bakhru Is your problem fully resolved now ? As I understand, you made 2 changes in code hcatConf.setVar(HiveConf.ConfVars.METASTORE_KERBEROS_KEYTAB_FILE, keytab); hcatConf.setVar(HiveConf.ConfVars.METASTORE_USE_THRIFT_SASL, "true"); and added commons-configuration-.x.x.jar to your classes. Can you confirm, so this question can be closed.

Thank You @mclark This is exactly what I was looking for.

@Rachna Bakhru Please see this. https://community.hortonworks.com/content/kbentry/17648/access-kerberos-cluster-from-java-using-cached-tic.html Do you kave keytab file for user that will be accessing cluster ? If yes, then you can use alternate approach of passing keytab and jaas file.

@Jesse Passwaters How are you loading your data to Hive ? If you are using Sqoop, then you need to take a look at https://sqoop.apache.org/docs/1.4.0-incubating/SqoopUserGuide.html#id1765770

Thank You @mclark for surfacing this. That really makes sense.

@Luis Size Please see https://cwiki.apache.org/confluence/display/AMBARI/Enhanced+Service+Dashboard to see how to create custom Ambari widgets. Also there are widgets available for HDFS/Yarn/HBase in Widget browser. Key is If the existing service in Ambari is pushing the metrics to Ambari metrics collector then minimal work needs to be done.
