[~lars_francke]
Would you mind providing a link or steps on how to update this patch? We have
been getting this alert on Ambari console for this on one of the data node
frequently, temp solution I will be restarting the journal node service and it
is ok. Then again appears in some time. Whether this has any impact on cluster
level like data write or read from data node? or it just a bug and there is no
impact? Your reply / help is much appreciated.
