Hi group, I have a problem using ProtocolBuffers 3 in my application with CDH5.6 HBase 1.0.
When creating BufferedMutator and flush data into HBase, it shows an error as below: java.lang.NoClassDefFoundError: Could not initialize class org.apache.hadoop.hbase.util.ByteStringer at org.apache.hadoop.hbase.protobuf.RequestConverter.buildRegionSpecifier(RequestConverter.java:995) at org.apache.hadoop.hbase.protobuf.RequestConverter.buildGetRowOrBeforeRequest(RequestConverter.java:138) at org.apache.hadoop.hbase.protobuf.ProtobufUtil.getRowOrBefore(ProtobufUtil.java:1579) at org.apache.hadoop.hbase.client.ConnectionManager$HConnectionImplementation.locateRegionInMeta(ConnectionManager.java:1293) at org.apache.hadoop.hbase.client.ConnectionManager$HConnectionImplementation.locateRegion(ConnectionManager.java:1125) at org.apache.hadoop.hbase.client.AsyncProcess.submit(AsyncProcess.java:369) at org.apache.hadoop.hbase.client.AsyncProcess.submit(AsyncProcess.java:320) at org.apache.hadoop.hbase.client.BufferedMutatorImpl.backgroundFlushCommits(BufferedMutatorImpl.java:198) at org.apache.hadoop.hbase.client.BufferedMutatorImpl.doMutate(BufferedMutatorImpl.java:141) at org.apache.hadoop.hbase.client.BufferedMutatorImpl.mutate(BufferedMutatorImpl.java:105) It looks like HBase is using ProtocolBuffers2.5, which cause the bytecode incompatible. Does anyone has experience of resolving this problem? Or I have to switch back to protocol 2.5.
