HIve MetaStore Event Listeners are used to Detect the every single event that takes place whenever an event is executed in hive, in case You want some action to take place for an event you can override MetaStorePreEventListener and provide it your own Implementation
in this article, we will learn how to create our own metastore event listeners in the hive using scala and sbt
so let’s get started first add the following dependencies in your build.sbt file
libraryDependencies += "org.apache.hive" % "hive-exec" % "1.2.1" excludeAll
ExclusionRule(organization = "org.pentaho")
libraryDependencies += "org.apache.hadoop" % "hadoop-common" % "2.7.3"
libraryDependencies += "org.apache.httpcomponents" % "httpclient" % "4.3.4"
libraryDependencies += "org.apache.hadoop" % "hadoop-client" % "2.6.0"
libraryDependencies += "org.apache.hive" % "hive-service" % "1.2.1"
unmanagedJars in Compile += file("/usr/lib/hive/lib/hive-exec-1.2.1.jar")
assemblyMergeStrategy in assembly := {
case PathList("META-INF", xs @ _*) => MergeStrategy.discard
case x => MergeStrategy.first
}
now create your first class you can be named it anything I named it…
