我在cd4下运行mapreduce作业时收到以下警告.
java.io.IOException:0秒的租约超时已过期.在org.apache.hadoop.hdfs.DFSOutputStream.abort(DFSOutputStream.java:1700)在org.apache.hadoop.hdfs.DFSClient.closeAllFilesBeingWritten(DFSClient.java:652)在org.apache.hadoop.hdfs.DFSClient.renewLease (DFSClient.java:604)在org.apache.hadoop.hdfs.LeaseRenewer.renew(LeaseRenewer.java:411)在org.apache.hadoop.hdfs.LeaseRenewer.run(LeaseRenewer.java:436)在org.apache. hadoop.hdfs.LeaseRenewer.access $ 700(LeaseRenewer.java:70)在org.apache.hadoop.hdfs.LeaseRenewer $ 1.run(LeaseRenewer.java:297)在java.lang.Thread.run(Thread.java:662)
知道这意味着什么吗？
