Log more details when a scanner lease expires

Key: HBASE-3850
URL: https://issues.apache.org/jira/browse/HBASE-3850
Project: HBase
Issue Type: Improvement
Components: regionserver
Reporter: Benoit Sigoure
Priority: Critical
Attachments: HBASE-3850.trunk.v1.patch
The message logged by the RegionServer when a Scanner lease expires isn't as
useful as it could be. {{Scanner 4765412385779771089 lease expired}} - most
clients don't log their scanner ID, so it's really hard to figure out what
was going on. I think it would be useful to at least log the name of the
region on which the Scanner was open, and it would be great to have the
ip:port of the client that had that lease too.

Request counters may become negative for heavily loaded regions

Issue Type: Bug
Affects Versions: 0.92.0
Reporter: Zhihong Yu
Assignee: Mubarak Seyed
Fix For: 0.94.0, 0.92.1
Requests counter showing negative count, example under 'Requests' column:
-645470239
{code}
Name Region Server Start Key End Key Requests
usertable,user2037516127892189021,1326756873774.16833e4566d1daef109b8fdcd1f4b5a6.

-645470239
{code}
RegionLoad.readRequestsCount and RegionLoad.writeRequestsCount are of int
type. Our Ops has been running lots of heavy load operation.
RegionLoad.getRequestsCount() overflows int.MAX_VALUE. It is set to D986E7E1.
In table.jsp, RegionLoad.getRequestsCount() is assigned to long type.
D986E7E1 is converted to long D986E7E1 which is -645470239 in decimal.
Suggested fix is to make readRequestsCount and writeRequestsCount long type.

hadoop-metrics.properties can include configuration of the rest context for
ganglia

Key: HBASE-4940
URL: https://issues.apache.org/jira/browse/HBASE-4940

Issue Type: Improvement
Components: metrics
Affects Versions: 0.90.5
Environment: HBase-0.90.1

Priority: Minor
Labels: hbase-rest
Fix For: 0.94.0
Attachments: HBASE-4940.patch, HBASE-4940.trunk.v1.patch
It appears from hadoop-metrics.properties that configuration for rest context
is missing. It would be good if we add the rest context and commented out
them, if anyone is using rest-server and if they want to monitor using
ganglia context then they can uncomment the rest context and use them for
rest-server monitoring using ganglia.
{code}
# Configuration of the rest context for ganglia
#rest.class=org.apache.hadoop.metrics.ganglia.GangliaContext
#rest.period=10
#rest.servers=ganglia-metad-hostname:port
{code}
Working on the patch, will submit it.
