用了key-value型的数据库cassandra一段时间了，这段时间这集群出现这个error: java.lang.RuntimeException: java.lang.RuntimeException: Could not reach schema agreement with /172.16.13.164 in 60000ms at org.apache.cassandra.utils.WrappedRunnable.run(WrappedRunnable.java:34) 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) Caused by: java.lang.RuntimeException: Could not reach schema agreement with /172.16.13.164 in 60000ms at org.apache.cassandra.db.HintedHandOffManager.waitForSchemaAgreement(HintedHandOffManager.java:256) at org.apache.cassandra.db.HintedHandOffManager.deliverHintsToEndpoint(HintedHandOffManager.java:267) at org.apache.cassandra.db.HintedHandOffManager.access$100(HintedHandOffManager.java:88) at org.apache.cassandra.db.HintedHandOffManager$2.runMayThrow(HintedHandOffManager.java:391) at org.apache.cassandra.utils.WrappedRunnable.run(WrappedRunnable.java:30) ... 3 more

哈哈,原来是集群中system库不同步的问题，问题已解决。 在早期发现创建column family 时会卡在那，没办法，唯好重整这个集群了，重新生成数据结构，再copy数据文件回去了。
