Hello, I am trying to run a pig job with mapreduce mode that tries to write to Hbase using PhoenixHBaseStorage.
I am seeing the reduce task fail with no suitable driver found for the connection. AttemptID:attempt_1436998373852_1140_r_000000_1 Info:Error: java.lang.RuntimeException: java.sql.SQLException: No suitable driver found for jdbc:phoenix:remoteclusterZkQuorum:2181; at org.apache.phoenix.mapreduce.PhoenixOutputFormat.getRecordWriter(PhoenixOutputFormat.java:58) at org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.PigOutputFormat.getRecordWriter(PigOutputFormat.java:88) at org.apache.hadoop.mapred.ReduceTask$NewTrackingRecordWriter.<init>(ReduceTask.java:540) at org.apache.hadoop.mapred.ReduceTask.runNewReducer(ReduceTask.java:614) at org.apache.hadoop.mapred.ReduceTask.run(ReduceTask.java:389) at org.apache.hadoop.mapred.YarnChild$2.run(YarnChild.java:168) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:422) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1576) at org.apache.hadoop.mapred.YarnChild.main(YarnChild.java:163) Caused by: java.sql.SQLException: No suitable driver found for jdbc:phoenix:jdbc:phoenix:remoteclusterZkQuorum:2181; at java.sql.DriverManager.getConnection(DriverManager.java:689) at java.sql.DriverManager.getConnection(DriverManager.java:208) at org.apache.phoenix.mapreduce.util.ConnectionUtil.getConnection(ConnectionUtil.java:93) at org.apache.phoenix.mapreduce.util.ConnectionUtil.getOutputConnection(ConnectionUtil.java:80) at org.apache.phoenix.mapreduce.util.ConnectionUtil.getOutputConnection(ConnectionUtil.java:68) at org.apache.phoenix.mapreduce.PhoenixRecordWriter.<init>(PhoenixRecordWriter.java:49) at org.apache.phoenix.mapreduce.PhoenixOutputFormat.getRecordWriter(PhoenixOutputFormat.java:55) I checked that the PhoenixDriver is on the classpath for the reduce task by adding a Class.forName("org.apache.phoenix.jdbc.PhoenixDriver") but the write still fails. Anyone else encountered an issue while trying Hbase writes via Pig in mapreduce mode. --Siddhi
