Hi @saranvisa and @csguna Thanks for your answers, But I still must to make a disicion about configuring a HDFS HA or not! My quesion is, if I will configure the HDFS HA with 2 diferent NN is it WORK or NOT ?! For performence I'll not have a problem because the two servers are very strong (in fact all the ressources in the two hosts far exceeds the recommendations configurations !). Thanks.

Hi, I found this phrases in the HDFS High Availability (HA) documentation, and I want to know if it obligatory or it's just a recommendation !!!? source: https://www.cloudera.com/documentation/enterprise/5-14-x/topics/cdh_hag_hdfs_ha_hardware_config.html NameNode hosts - These are the hosts on which you run the active and standby NameNodes. They should have equivalent hardware to each other the host that is chosen should have the same hardware configuration (RAM, disk space, number of cores, and so on) as the active NameNode. source: https://www.cloudera.com/documentation/enterprise/5-14-x/topics/cdh_hag_hdfs_ha_enabling.html#cmug_topic_5_12 Thanks in adcance.

Hi @mauricio I think the solution is sample, you must to SET DISABLE_CODEGEN to true! also it's advised by cloudera documentation!! source: https://www.cloudera.com/documentation/enterprise/latest/topics/impala_disable_codegen.html Good luck.

HI @VJM You shold use the cast function: select cast(s.conferencedatetime as TIMESTAMP) as starttime from session s; Good luck.

Hi @Tomas79 Unfortunately no, COMPUTE INCREMENTAL STATS only applies to partitioned HDFS tables. source: https://www.cloudera.com/documentation/enterprise/latest/topics/impala_compute_stats.html
