hbase 啓動 Error: Could not find or load main class org.apache.hadoop.hbase.util.HBaseConfTool

 安裝好hadoop，而後安裝hbase啓動時出現問題，下面是報錯信息：

./hbase/bin/start-hbase.sh
Error: Could not find or load main class org.apache.hadoop.hbase.util.HBaseConfTool
Error: Could not find or load main class org.apache.hadoop.hbase.zookeeper.ZKServerTool
starting master, logging to /usr/local/hbase/logs/hbase-root-master-localhost.out
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=128m; support was removed in 8.0
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=128m; support was removed in 8.0
Error: Could not find or load main class org.apache.hadoop.hbase.master.HMaster
starting regionserver, logging to /usr/local/hbase/logs/hbase-root-1-regionserver-localhost.out
Error: Could not find or load main class org.apache.hadoop.hbase.regionserver.HRegionServer

分析：啓動時找不到類文件，搜了好多有的說是classpath環境變量問題，最後終於找到了問題所在，因爲下的是src文件 即未編譯的文件，不能直接用，必須先編譯，從新下載bin文件 即二進制文件。

而後把須要的配置配好從新啓動

start-hbase.sh 
running master, logging to /usr/local/hadoop-2.6.5/hbase-1.4.9/logs/hbase--master-masternode.out
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=128m; support was removed in 8.0
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=128m; support was removed in 8.0

slave2: running regionserver, logging to /usr/local/hadoop-2.6.5/hbase-1.4.9/logs/hbase-root-regionserver-slave2.out

總結：這麼簡單的問題也不會有人出現了，因此最後都沒搜到有效的問題解決方法，記錄一下引覺得戒。
