@Sunile Manjee It may be related to client time zone TIMESTAMP The timestamp data type. The format is yyyy- MM -dd hh:mm:ss[.nnnnnnnnn]. Mapped to java.sql.Timestamp with an internal representation of the number of nanos from the epoch. The binary representation is 12 bytes: an 8 byte long for the epoch time plus a 4 byte integer for the nanos. Note that the internal representation is based on a number of milliseconds since the epoch (which is based on a time in GMT ), while java.sql.Timestamp will format timestamps based on the client's local time zone. Example: TIMESTAMP ... View more

@Zack Riesland You can compare those clients with mysql or oracle client for the better understanding. HDP client libraries are Java libraries that facilitate communication from a remote host. An HDP client library has all the HDP JAR files on it for communicating with Hive, HDFS, etc. Note that you will not find any HDP service running on the client host machine. Will a data node still be leveraged for a Tez query if it doesn't have a Tez Client? Yes How is the YARN client different from a NodeManager? NodeManager (NM) is YARN’s per-node agent, and takes care of the individual compute nodes in a Hadoop cluster. This includes keeping up-to date with the ResourceManager (RM), overseeing containers’ life-cycle management; monitoring resource usage (memory, CPU) of individual containers, tracking node-health, log’s management and auxiliary services which may be exploited by different YARN applications. Yarn client is just command line tool What is a zookeeper client? Its just zookeeper command line tool. ... View more
