Hitting the JanusGraphException when loading vertexes
We are seeing the following exception when running the janusgraph-utils to import vertexes: 14:10:22,084 INFO VertexLoaderWorker:122 - Starting new thread ff35bb84-73e7-4482-b7e5-5eb93c15485e 14:10:24,314 ERROR StandardJanusGraph:740 - Could not commit transaction [20774] due to storage exception in commit org.janusgraph.core.JanusGraphException: Could not execute operation due to backend exception at org.janusgraph.diskstorage.util.BackendOperation.execute(BackendOperation.java:57) at org.janusgraph.diskstorage.keycolumnvalue.cache.CacheTransaction.persist(CacheTransaction.java:95) at org.janusgraph.diskstorage.keycolumnvalue.cache.CacheTransaction.flushInternal(CacheTransaction.java:143) at org.janusgraph.diskstorage.keycolumnvalue.cache.CacheTransaction.commit(CacheTransaction.java:200) at org.janusgraph.diskstorage.BackendTransaction.commitStorage(BackendTransaction.java:134) at org.janusgraph.graphdb.database.StandardJanusGraph.commit(StandardJanusGraph.java:737) at org.janusgraph.graphdb.transaction.StandardJanusGraphTx.commit(StandardJanusGraphTx.java:1374) at com.ibm.janusgraph.utils.importer.vertex.VertexLoaderWorker.acceptRecord(VertexLoaderWorker.java:109) at com.ibm.janusgraph.utils.importer.vertex.VertexLoaderWorker.access$000(VertexLoaderWorker.java:35) at com.ibm.janusgraph.utils.importer.vertex.VertexLoaderWorker$1.accept(VertexLoaderWorker.java:130) at com.ibm.janusgraph.utils.importer.vertex.VertexLoaderWorker$1.accept(VertexLoaderWorker.java:126) at java.util.ArrayList$Itr.forEachRemaining(ArrayList.java:899) at com.ibm.janusgraph.utils.importer.vertex.VertexLoaderWorker.run(VertexLoaderWorker.java:126) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: org.janusgraph.diskstorage.PermanentBackendException: Permanent failure in storage backend at org.janusgraph.diskstorage.cassandra.thrift.CassandraThriftKeyColumnValueStore.convertException(CassandraThriftKeyColumnValueStore.java:263) at org.janusgraph.diskstorage.cassandra.thrift.CassandraThriftStoreManager.mutateMany(CassandraThriftStoreManager.java:315) at org.janusgraph.diskstorage.locking.consistentkey.ExpectedValueCheckingStoreManager.mutateMany(ExpectedValueCheckingStoreManager.java:79) at org.janusgraph.diskstorage.keycolumnvalue.cache.CacheTransaction$1.call(CacheTransaction.java:98) at org.janusgraph.diskstorage.keycolumnvalue.cache.CacheTransaction$1.call(CacheTransaction.java:95) at org.janusgraph.diskstorage.util.BackendOperation.executeDirect(BackendOperation.java:69) at org.janusgraph.diskstorage.util.BackendOperation.execute(BackendOperation.java:55) ... 17 more Caused by: TimedOutException(acknowledged_by:0, acknowledged_by_batchlog:true) at org.apache.cassandra.thrift.Cassandra$atomic_batch_mutate_result$atomic_batch_mutate_resultStandardScheme.read(Cassandra.java:29624) at org.apache.cassandra.thrift.Cassandra$atomic_batch_mutate_result$atomic_batch_mutate_resultStandardScheme.read(Cassandra.java:29592) at org.apache.cassandra.thrift.Cassandra$atomic_batch_mutate_result.read(Cassandra.java:29526) at org.apache.thrift.TServiceClient.receiveBase(TServiceClient.java:78) at org.apache.cassandra.thrift.Cassandra$Client.recv_atomic_batch_mutate(Cassandra.java:1108) at org.apache.cassandra.thrift.Cassandra$Client.atomic_batch_mutate(Cassandra.java:1094) at org.janusgraph.diskstorage.cassandra.thrift.CassandraThriftStoreManager.mutateMany(CassandraThriftStoreManager.java:310) ... 22 more
Any help on debugging this will be greatly appreciated. I have tried searching for this exception but to not much luck. Please note we are running on janusgraph 0.2.0 and cassandra is running locally with janusgraph and elasticsearch.
