Cassandra reboot Error Java.lang.ClassCastException-

Several tables have been created through CQL, such as:

CREATE TABLE fileindex (recid varchar,agentno varchar,customerno varchar,recfile varchar,createtime varchar, PRIMARY KEY (recid)); CREATE INDEX on FileIndex (AGENTNO); CREATE INDEX on FileIndex (Customerno); CREATE INDEX on FileIndex (recfile); CREATE INDEX on FileIndex (createtime);

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; then insert a number of data in the table, after running for a period of time, restart Cassandra, reported the following error:

Java.lang.ClassCastException:java.math.BigInteger cant be cast to Java.nio.ByteBufferat Org.apache.cassandra.db.marshal.UTF8Type.compare (utf8type.java:27) at Org.apache.cassandra.dht.LocalToken.compareTo (localtoken.java:45) at Org.apache.cassandra.db.DecoratedKey.compareTo (decoratedkey.java:89) at Org.apache.cassandra.db.DecoratedKey.compareTo (decoratedkey.java:38) at Java.util.TreeMap.getEntry (Treemap.java : 328) at Java.util.TreeMap.containsKey (treemap.java:209) at Java.util.TreeSet.contains (treeset.java:217) at Org.apache.cassandra.io.sstable.SSTableReader.load (sstablereader.java:396) at Org.apache.cassandra.io.sstable.SSTableReader.open (sstablereader.java:187) at Org.apache.cassandra.io.sstable.sstablereader$1.run (sstablereader.java:225) at java.util.concurrent.executors$ Runnableadapter.call (executors.java:441) at Java.util.concurrent.futuretask$sync.innerrun (FutureTask.java:303) at Java.util.concurrent.FutureTask.run (futuretask.java:138) at Java.util.concurrent.threadpoolexecutor$worker.runtaSK (threadpoolexecutor.java:886) at Java.util.concurrent.threadpoolexecutor$worker.run (ThreadPoolExecutor.java : 908) at Java.lang.Thread.run (thread.java:662) java.lang.ClassCastException:java.math.BigInteger cant is cast to Java.nio.ByteBufferat Org.apache.cassandra.db.marshal.UTF8Type.compare (utf8type.java:27) at Org.apache.cassandra.dht.LocalToken.compareTo (localtoken.java:45) at Org.apache.cassandra.db.DecoratedKey.compareTo (decoratedkey.java:89) at Org.apache.cassandra.db.DecoratedKey.compareTo (decoratedkey.java:38)

Looking for a long time, finally found the answer, the original is Cassandra1.1.1 a bug (will be repaired in Cassandra1.1.2).

https://issues.apache.org/jira/browse/CASSANDRA-4331

The workaround is to delete the files in the Saved_caches_directory folder, the default location is/var/lib/cassandra/saved_caches

and then reboot.
