Uma Maheswara Rao G commented on HDFS-2892:
-------------------------------------------
Hey Brahma,
Thanks for checking.
Can you please keep description short and add remaining details in comment.
Otherwise it will generate big email for every update.
{quote}Small clarification for following property..if some value configured
this then NN will be safe mode upto this much time..
May I know usage of the following property...
<property>
<name>dfs.blockreport.initialDelay</name> <value>0</value>
<description>Delay for first block report in seconds.</description>
</property>
{quote}
This property is to send the block report when starting up the system. If you
mention this delay more, then initial block report will take tame(delay you
configured)..
Also i would suggest that, this kind of clarification questions can be asked in
mailing list.
