新的HBase安裝非常慢

我剛在我的iMac上安裝了HBase 0.94.2，運行Sun Java 7和Mac OS 10.8.2。新的HBase安裝非常慢

我確實有一個開發Hadoop實例，但是現在我正在獨立模式下運行HBase。

不幸的是，許多基本的操作接管30秒，執行：

magoo:bin mattpainter$ ./hbase shell 
HBase Shell; enter 'help<RETURN>' for list of supported commands. 
Type "exit<RETURN>" to leave the HBase Shell 
Version 0.94.2, r1395367, Sun Oct 7 19:11:01 UTC 2012 

hbase(main):002:0> list 'table' 
TABLE                                          
2012-10-20 08:26:38.903 java[41217:1703] Unable to load realm info from SCDynamicStore 
0 row(s) in 33.6460 seconds 

hbase(main):003:0>

在日誌來看，我們可以看到這一點：

12/10/20 08:24:58 INFO zookeeper.ClientCnxn: Client session timed out, have not heard from server in 26667ms for sessionid 0x13a7a7744270005, closing socket connection and attempting reconnect

可能是有什麼錯的是一個徹頭徹尾的零配置（除了設置JAVA_HOME在hbase-env.sh之外）的盒子安裝會表現出這種行爲？

非常感謝，馬特
