Hbase HMasterが実行されていない

HBaseで問題が発生しています。私がhadoopを起動しようとすると、問題なしで起動します。しかし、HBaseは動作しません。DataNode、HRegionServer、secondaryNameNodeなどはすべて動作していますが、hbaseを起動するとHMasterは実行されません。 xyz。それを最初にやめてください。奇妙なことに、HBaseのログに「Matser started」と表示されていますが、確認すると始まりません。私は問題を探していますが、理解できません。Hbase HMasterが実行されていない

私が思うに、ログからこのライン、

2012-04-04 17:48:52,204 INFO org.apache.hadoop.ipc.Client: Retrying connect to server: localhost/127.0.0.1:54310. Already tried 0 time(s).

は、ポート54310で名前ノードに接続するために抱き合わせていると失敗していると述べています。

ブラウザでこれを入力して、使用している正確なポート番号を教えてください。

**http://localhost:50070**

あなたは名前ノードのようなものがわかります 'localhostと:?'を最初の行に、 '？ 'はあなたのnamenodeポートです。

下記のHBaseのログは、あなたはiptablesのメートルのように、

netstat -nltp

またはあなたのファイアウォールでリスニングポートを確認することができこれも原因です。

時々、Hbaseが期待どおりに動作しないため、すべてのことを行った後でも...いくつかの理由があるかもしれません。時々、設定を行う際に何か不足していることがあります。動作しません。あなたが提供したログは、HMasterがネーム・ノードと通信できないことを示します。/ etc/hostsファイルを参照してください。 "127.0.1.1"を削除し、 "127.0.0.1"にしてください。あなたのHADOOP_HOMEとHADOOP_HOME/libディレクトリの "common-configurations" jarファイルをHbase/libディレクトリにコピーします。また、core-site.xmlとhbase-site.xmlのプロパティを一度チェックしてください。

これは過去6か月間正常に機能していました。しかし今はその主人が私たちにいくつかの問題を引き起こしている –

擬似分散モードでhbaseを設定しようとしている場合、これはおそらく$ PATHにhadoopを追加する原因になります。

$ PATHからhadoop homeを削除するだけで、hbaseを疑似分散モードで起動することができます。

デフォルトでは、hadoop homeを.bashrcに追加する人がいます。

あなたが.bashrcに追加されている場合は、そこからhadoopのホームを削除します。
