启动azkaban的server和executor时报了一个Error:Could not initialize class org.apache.derby.jdbc.AutoloadedDriver40 https://blog.csdn.net/int_double/article/details/80856107

最近在用azkaban跑项目时，报了一个Error:

                                                      java.lang.NoClassDefFoundError:  Could not initialize class org.apache.derby.jdbc.AutoloadedDriver40

                                                导致的原因：

                                                       在azkaban的server和executor中缺少一个叫derby.jar的包

                                                解决的方法：

                                                       把jdk/db/lib/derby.jar拷贝到azkaban的server和executor下的extlib下，这个Error就没了。
