Hi, I'm executing a workload on YCSB (50% read, 50% update) and after few minutes I get the following exception:
*TimedOutException()* * at org.apache.cassandra.thrift.Cassandra$get_slice_result.read(Cassandra.java:7174) * * at org.apache.cassandra.thrift.Cassandra$Client.recv_get_slice(Cassandra.java:540) * * at org.apache.cassandra.thrift.Cassandra$Client.get_slice(Cassandra.java:512)* * at com.yahoo.ycsb.db.CassandraClient10.read(CassandraClient10.java:259)* * at com.yahoo.ycsb.DBWrapper.read(DBWrapper.java:84)* * at com.yahoo.ycsb.workloads.CoreWorkload.doTransactionRead(CoreWorkload.java:469) * * at com.yahoo.ycsb.workloads.CoreWorkload.doTransaction(CoreWorkload.java:425)* * at com.yahoo.ycsb.ClientThread.run(ClientThread.java:105) * I have 2 seeds on Amazon EC2 (large instance) and depending on the demand, I add (or remove) new large instances. Any suggestion to solve this problem or to tune cassandra? Follows further info about cassandra installed. Thanks in advance. *INFO 00:54:05,591 JVM vendor/version: Java HotSpot(TM) 64-Bit Server VM/1.7.0_07* * INFO 00:54:05,592 Heap size: 1931476992/1931476992* *INFO 00:54:07,447 Cassandra version: 1.1.5* * INFO 00:54:07,448 Thrift API version: 19.32.0* Att. *Rodrigo Felix de Almeida* LSBD - Universidade Federal do Ceará Project Manager MBA, CSM, CSPO, SCJP
