> Key: HBASE-16469
> URL: https://issues.apache.org/jira/browse/HBASE-16469
> Project: HBase
> Issue Type: Improvement
> Components: Operability
> Affects Versions: 1.2.5
> Reporter: Nemo Chen
> Assignee: Nemo Chen
> Labels: easyfix, easytest
> Fix For: 2.0.0, 1.5.0
>
> Attachments: HBASE-16469.master.001.patch
>
>
> *method invocation replaced by variable*
> hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/handler/CloseRegionHandler.java
> {code}String name = regionInfo.getRegionNameAsString();{code}
> {code}LOG.warn("Can't close region: was already closed during close(): " +
> regionInfo.getRegionNameAsString()); {code}
> In the above two examples, the method invocations are assigned to the
> variables before the logging code. These method invocations should be
> replaced by variables in case of simplicity and readability
> ----
> *method invocation in return statement*
> hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegion.java
> {code}
> public String toString() {
> return getRegionInfo().getRegionNameAsString();
> }
> {code}
> {code}
> LOG.debug("Region " + getRegionInfo().getRegionNameAsString()
> + " is not mergeable because it is closing or closed");
> {code}
> {code}
> LOG.debug("Region " + getRegionInfo().getRegionNameAsString()
> + " is not mergeable because it has references");
> {code}
> {code}
> LOG.info("Running close preflush of " +
> getRegionInfo().getRegionNameAsString());
> {code}
> In these above examples, the "getRegionInfo().getRegionNameAsString())" is
> the return statement of method "toString" in the same class. They should be
> replaced with “this” in case of simplicity and readability.
> ----
> *check the logged variable if it is null*
> hbase-it/src/test/java/org/apache/hadoop/hbase/HBaseClusterManager.java
> {code}
> if ((sshUserName != null && sshUserName.length() > 0) ||
> (sshOptions != null && sshOptions.length() > 0)) {
> LOG.info("Running with SSH user [" + sshUserName + "] and options [" +
> sshOptions + "]");
> }
> {code}
> hbase-server/src/main/java/org/apache/hadoop/hbase/master/AssignmentManager.java
> {code}
> if ((regionState == null && latestState != null)
> || (regionState != null && latestState == null)
> || (regionState != null && latestState != null
> && latestState.getState() != regionState.getState())) {
> LOG.warn("Region state changed from " + regionState + " to "
> + latestState + ", while acquiring lock");
> }
> {code}
> In the above example, the logging variable could null at run time. It is a
> bad practice to include null variables inside logs.
> ----
> *variable in byte printed directly*
> hbase-server/src/test/java/org/apache/hadoop/hbase/util/MultiThreadedUpdater.java
> {code}
> byte[] rowKey = dataGenerator.getDeterministicUniqueKey(rowKeyBase);
> {code}
> {code}
> LOG.error("Failed to update the row with key = [" + rowKey
> + "], since we could not get the original row");
> {code}
> rowKey should be printed as Bytes.toString(rowKey).
> ----
> *object toString contain mi*
> The toString method returns getServerName(), so the "server.getServerName()"
> should be replaced with "server" in case of simplicity and readability.
> hbase-client/src/main/java/org/apache/hadoop/hbase/client/PreemptiveFastFailInterceptor.java
> {code}
> LOG.info("Clearing out PFFE for server " + server.getServerName());
> return getServerName();
> {code}
