按照文件配置、啟動，啟動的時候報錯，

1、在bin下，啟動./azkaban-web-start.sh報錯

2、報錯

6.0/conf:/home/hadoop/hadoop-2.6.0/*:/conf:/lib/*
[[email protected] bin]# Invalid maximum heap size: -Xmx4G
The specified size exceeds the maximum representable size.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit

 

是自己在啟動配置中的大小超出；設定azkaban-web-start.sh中Xmx4G改成512M；

AZKABAN_OPTS="-Xmx512M"

同理，在啟動executor的時候也會報錯，同樣改為512M，

而上面的命令bin./azkaban-web-start.sh換成在bin下啟動./azkaban-web-start.sh出現報錯關鍵在於Caused by: java.lang.IllegalArgumentException: User xml file conf/azkaban-users.xml doesn't exist.

原因是在

vi azkaban.properties中，路徑寫的是相對路徑，所以如果不改動路徑，那麼就得在正確的路徑下啟動命令，如在server中啟動，用bin./azkaban-web-start.sh

問題就可解決
