Description

I setup a new 1.4.1 instance that was running on top of a Hadoop installation that had the maximum block replications set to 3 and the following error showed up on the monitor page.

java.io.IOException: failed to create file /accumulo/tables/!0/table_info/F0000001.rf_tmp on client 127.0.0.1. Requested replication 5 exceeds maximum 3 at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.startFileInternal(FSNamesystem.java:1220) at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.startFile(FSNamesystem.java:1123) at org.apache.hadoop.hdfs.server.namenode.NameNode.create(NameNode.java:551) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.ipc.RPC$Server.call(RPC.java:523) at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:1383) at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:1379) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:396) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1059) at org.apache.hadoop.ipc.Server$Handler.run(Server.java:1377)

Tablet server error is:
