Subject [jira] [Updated] (HDFS-8808) dfs.image.transfer.bandwidthPerSec should not apply to -bootstrapStandby
Date Thu, 13 Aug 2015 06:10:46 GMT

Zhe Zhang updated HDFS-8808:
----------------------------
    Attachment: HDFS-8808-03.patch

Updating patch to fix whitespace issue (it was actually not caused by the patch, fixing anyway).

{{TestReplaceDatanodeOnFailure}} is unrelated to the change and passes locally.

> The parameter {{dfs.image.transfer.bandwidthPerSec}} can be used to limit the speed with
which the fsimage is copied between the namenodes during regular use. However, as a side effect,
this also limits transfers when the {{-bootstrapStandby}} option is used. This option is often
used during upgrades and could potentially slow down the entire workflow. The request here
is to ensure {{-bootstrapStandby}} is unaffected by this bandwidth setting
