Jimmy Xiang commented on HBASE-9116:
------------------------------------
I see several places warning is logged like this:
{noformat}
+ LOG.warn("Cannot place the favored nodes for region "
+ + regionInfo.getRegionNameAsString() + " because " + e);
{noformat}
Perhaps, it is better to log the stack trace as well:
{noformat}
+ LOG.warn("Cannot place the favored nodes for region "
+ + regionInfo.getRegionNameAsString() + " because " + e, e);
{noformat}
Some function may not throw exception declared, for example,
FavoredNodeAssignmentHelper#placeSecondaryAndTertiaryWithRestrictions doesn't
throw IOException.
Good stuff. Is this still WIP? How can we use this? Edit the meta table from
hbase shell?
