I’m attempting to connect to Hive via R and RJDBC. Kicking some tires – eventually, I’ll go with RHive and RHadoop.
I’m using HDP-2.1.2, R 3.1.0, and RJDBC-0.2-3.
Does anyone have a minimal working R script do do this? I’m able to trying to establish a connection and running into:
> conn = dbConnect(drv, drvUrl, creds$uid, NULL)
Error in .jcall(drv@jdrv, “Ljava/sql/Connection;”, “connect”, as.character(url)[1], :
java.lang.NoClassDefFoundError: Could not initialize class org.apache.thrift.transport.TSocket
>
> tryCatch(dbConnect(drv, drvUrl, creds$uid, NULL), Error = function(e){e$jobj$printStackTrace()})
java.lang.NoClassDefFoundError: Could not initialize class org.apache.thrift.transport.TSocket
at org.apache.hadoop.hive.jdbc.HiveConnection.<init>(HiveConnection.java:111)
at org.apache.hadoop.hive.jdbc.HiveDriver.connect(HiveDriver.java:106)
I think this means I’m missing something from my classpath, and that is causing an error while initializing TSocket. My class path is:
