There is no ntpupdate command. You can update ntp by typing # ntpdate -u {Main node sync'ed to NTP server IP address or Domain name here} Example # ntpdate -u domains.ntp.com OR # ntpdate -u 192.168.0.2 You should only have 1 node announcing NTP and other nodes getting time from main node.

I use puppet and foreman to configure each system the same for all ntp clients to a central ntp server. Great information here http://www.linuxsecrets.com/blog/4tutorial-and-install-howto/2014/06/26/906-how-to-install-and-configure-linux-ntp-server-and-client

Hi anton_85 Try this article, it explains time zones and settings which is very well explained. http://www.linuxsecrets.com/easyblog/2015/01/30/1374-fixing-date-and-setting-time-and-zone-on-rhel-6-from-command-line

I just did a roll back which resolved the issue. We have been testing apache hadoop as well so that's why I was delayed to answer. Thanks

What can I check to resolve this issue? Had someone changing stuff and have no idea what they did to kill my hadoop cloudera. 15/04/13 16:28:18 INFO mapred.FileInputFormat: Total input paths to process : 10 15/04/13 16:28:18 INFO mapred.JobClient: Running job: job_201504131620_0001 15/04/13 16:28:19 INFO mapred.JobClient: map 0% reduce 0% 15/04/13 16:28:22 INFO mapred.JobClient: Task Id : attempt_201504131620_0001_m_000011_0, Status : FAILED java.lang.Throwable: Child Error at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:250) Caused by: java.io.IOException: Task process exit with nonzero status of 2. at org.apache.hadoop.mapred.TaskRunner.run(TaskRunner.java:237)

Hi eafonsof Updating your kernel version will resolve the issue most likely. I updated mine to kernel 3.18.x and resolved the issue.

I can document the process for CentOS if you like. It's pretty much the same with RedHat as well. Only difference is the repo and versions. Let me know if you want it documented then I'll post it somewhere for you.

P.S. Don't forget to create or move your current .config from previous kernel or create new .config. # cd /usr/src/kernels/linux-3.18.8 # cp ../linux-old-kernel-version/.config . # make oldconfig -j32;make modules -j32;make modules_install -j32;make install # Answer all question using just the default. Just enter through the kernel questions.

Just change the versioning number from kernel or update to RedHat 6.6. 6.6 works perfectly. Down grading isn't a good option in my opinion. It's simply needs a version check which you can do by just upgrading the kernel version. Easiest way instead of doing a complete reinstall or downgrade which isn't a good option. Download kernel from kernel.org # cd /usr/src/kernels # wget https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.18.8.tar.gz # tar zxvf linux-3.18.8.tar.gz # cd linux-3.18.8 # make -j32;make modules -j32;make modules_install -j32;make install # edit /boot/grub/grub.cfg Change to 0 which is the current kernel version and that's it, reboot and you're set.
