> *method invocation replaced by variable*
> hbase-1.2.2/hbase-server/src/main/java/org/apache/hadoop/hbase/backup/example/LongTermArchivingHFileCleaner.java
> line 57: {code}Path file = fStat.getPath();{code}
> line 74: {code}LOG.error("Failed to lookup status of:" + fStat.getPath() + ",
> keeping it just incase.", e); {code}
> hbase-1.2.2/hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/handler/CloseRegionHandler.java
> line 118: {code}String name = regionInfo.getRegionNameAsString();{code}
> line 142: {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-1.2.2/hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegion.java
> line 5455:
> {code}
> public String toString() {
> return getRegionInfo().getRegionNameAsString();
> }
> {code}
> line 1260:
> {code}
> LOG.debug("Region " + getRegionInfo().getRegionNameAsString()

> {code}
> line 1265:
> {code}
> LOG.debug("Region " + getRegionInfo().getRegionNameAsString()

> {code}
> line 1413:
> {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-1.2.2/hbase-it/src/test/java/org/apache/hadoop/hbase/HBaseClusterManager.java
> line 88:
> {code}
> if ((sshUserName != null && sshUserName.length() > 0) ||

> 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-1.2.2/hbase-server/src/test/java/org/apache/hadoop/hbase/util/MultiThreadedUpdater.java
> line 145:
> {code}

> line 184:
> {code}
> LOG.error("Failed to update the row with key = [" + rowKey

> {code}
> rowKey should be printed as Bytes.toString(rowKey).
> ----
> *object toString contain mi*
> hbase-1.2.2/hbase-client/src/main/java/org/apache/hadoop/hbase/client/AsyncProcess.java
> {code}
> LOG.warn("#" + id + ", the task was rejected by the pool. This is
> unexpected."+ " Server is "+ server.getServerName(),t);
> {code}
> server is an instance of class ServerName, we found ServerName.java:
> hbase-client/src/main/java/org/apache/hadoop/hbase/ServerName.java
> {code}
> @Override
> public String toString() {
> return getServerName();
> }
> {code}
> the toString method returns getServerName(), so the "server.getServerName()"
> should be replaced with "server" in case of simplicity and readability
> Similar examples are in:
> hbase-1.2.2/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}
> hbase-1.2.2/hbase-server/src/main/java/org/apache/hadoop/hbase/ipc/RpcServer.java
> line 705:
> {code} LOG.debug(getName() + ": disconnecting client " + c.getHostAddress());
> {code}
> line 1259:
> {code}
> public String toString() {
> return getHostAddress() + ":" + remotePort;
