Duong updated HDDS-9516:
------------------------
Description:
The following "ozone.scm.datanode.pipeline.limit" is now 2 by default, which
needs to be tweaked every time a customer have more than 2 volumes in their
datanodes. This should be 0 by default to allow SCM to set the limit based on
the number of datanode volumes.
{code:java}
<name>ozone.scm.datanode.pipeline.limit</name>
<value>2</value>
<tag>OZONE, SCM, PIPELINE</tag>
<description>Max number of pipelines per datanode can be engaged in.
Setting the value to 0 means the pipeline limit per dn will be determined
by the no of metadata volumes reported per dn.

</property> {code}
