Hi all, I installed a redhat_enterprise-linux-x86 in VMware Workstation, and set the virtual machine 1G memory.
Then I followed steps guided by "Installing CDH4 on a Single Linux Node in Pseudo-distributed Mode" —— https://ccp.cloudera.com/display/CDH4DOC/Installing+CDH4+on+a+Single+Linux+Node+in+Pseudo-distributed+Mode. When at last, I ran an example Hadoop job with the command "$ hadoop jar /usr/lib/hadoop-mapreduce/hadoop-mapreduce-examples.jar grep input output23 'dfs[a-z.]+'" then the screen showed as follows, depending "AttemptID:attempt_1360528029309_0001_r_000000_0 Timed out after 600 secs" and I wonder is that because my virtual machine's memory too little~~??
