Hi, all I tried to write data to HBase in a Spark-1.0 rc8 application,
the application is terminated due to the java.lang.IllegalAccessError, Hbase shell works fine, and the same application works with a standalone Hbase deployment java.lang.IllegalAccessError: com/google/protobuf/HBaseZeroCopyByteString at org.apache.hadoop.hbase.protobuf.RequestConverter.buildRegionSpecifier(RequestConverter.java:930) at org.apache.hadoop.hbase.protobuf.RequestConverter.buildGetRowOrBeforeRequest(RequestConverter.java:133) at org.apache.hadoop.hbase.protobuf.ProtobufUtil.getRowOrBefore(ProtobufUtil.java:1466) at org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation.locateRegionInMeta(HConnectionManager.java:1236) at org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation.locateRegion(HConnectionManager.java:1110) at org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation.locateRegion(HConnectionManager.java:1067) at org.apache.hadoop.hbase.client.AsyncProcess.findDestLocation(AsyncProcess.java:356) at org.apache.hadoop.hbase.client.AsyncProcess.submit(AsyncProcess.java:301) at org.apache.hadoop.hbase.client.HTable.backgroundFlushCommits(HTable.java:955) at org.apache.hadoop.hbase.client.HTable.flushCommits(HTable.java:1239) at org.apache.hadoop.hbase.client.HTable.close(HTable.java:1276) at org.apache.hadoop.hbase.mapreduce.TableOutputFormat$TableRecordWriter.close(TableOutputFormat.java:112) at org.apache.spark.rdd.PairRDDFunctions.org$apache$spark$rdd$PairRDDFunctions$$writeShard$1(PairRDDFunctions.scala:720) at org.apache.spark.rdd.PairRDDFunctions$$anonfun$saveAsNewAPIHadoopDataset$1.apply(PairRDDFunctions.scala:730) at org.apache.spark.rdd.PairRDDFunctions$$anonfun$saveAsNewAPIHadoopDataset$1.apply(PairRDDFunctions.scala:730) at org.apache.spark.scheduler.ResultTask.runTask(ResultTask.scala:111) at org.apache.spark.scheduler.Task.run(Task.scala:51) at org.apache.spark.executor.Executor$TaskRunner.run(Executor.scala:187) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:744) Can anyone give some hint to the issue?
