How frequent kicks HDFS balancer

[#1]

hi experts!

in HDFS serivices there is tool called balancer, which purposed to ensure even distribution of blocks across cluster.

my question is how frequently it kicks in to check is cluster imbalanced or not?

is there any way to change this frequency?

thanks!

The command in CM -> HDFS -> Actions to run Balancer is ad-hoc.
There's no schedule it runs by - you'll need to invoke it manually to
trigger the HDFS Balancer work.

If you'd like to setup a frequency, you can use the CM API to trigger
it via crontab/etc.
