Hi all, I'm trying to deploy an EndPoint Coprocessor I wrote. This isn't the first one I'm writing and deploying but I can't seem to find the problem here. I pack the code in a JAR, copy it to HDFS and load it to the table from shell (with full URI of course).
When I try to execute the endpoint (which execute a scan using InternalScanner) I get nothing for a few seconds and then I get exceptions: HConnectionImplementation ยป Error executing for row "start_key" RetriesExhaustedException: Failed after attempts=10, exceptions: IOException: IPC server unable to read call parameters: Error in readFields.......*10 times* * * at java.util.concurrent.FutureTask$Sync.innerGet(FutureTask.java:252) at java.util.concurrent.FutureTask.get(FutureTask.java:111) at org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation.processExecs(HConnectionManager.java:1453) at org.apache.hadoop.hbase.client.HTable.coprocessorExec(HTable.java:1236) at org.apache.hadoop.hbase.client.HTable.coprocessorExec(HTable.java:1216) at org.apache.hadoop.hbase.client.HTablePool$PooledHTable.coprocessorExec(HTablePool.java:481) at com.infolinks.redmap.services.impl.utils.TestExecutor.testHBaseCPScan(TestExecutor.java:171) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) Is there something I missed in deployment ? Thanks, Amit.
