Hi@Shllpa,

Are you able to configure HA proxy in your system? I mean not for MR. How HA proxy works?

 No HA proxy I am nt able to bec that links talk about MapR env .Our deployment is open source apache hadoop 2.6.5.

Would like to know is that possible by setting HA proxy .if so any pointers to install ?Please share

Hi,

If you are trying to balance the load of Jobhistory server, then just mention the IP addresses in HA proxy configuration file.

Thank you so much :)  .But here some more query sorry for taking your time .

Installing mapreduce daemons alone is not possible right ? especially from ambari UI 2.6.5  or can we ??

Hi@Shllpa,

I think it is not possible. You need to configure first. Did you try the above solution?
