Storm's configuration file format is prone to errors, which causes Storm to fail to start correctly. The error messages caused by the format are generally as follows:
Exception in thread "main" java.lang.ExceptionInInitializerError at org.apache.storm.config$read_storm_config.invoke(config.clj:78) at org.apache.storm.config$fn__906.invoke(config.clj:100) at org.apache.storm.config__init.load(Unknown Source) at org.apache.storm.config__init.<clinit>(Unknown Source) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:348) at clojure.lang.RT.classForName(RT.java:2154) at clojure.lang.RT.classForName(RT.java:2163) at clojure.lang.RT.loadClassForName(RT.java:2182) at clojure.lang.RT.load(RT.java:436) at clojure.lang.RT.load(RT.java:412) at clojure.core$load$fn__5448.invoke(core.clj:5866) at clojure.core$load.doInvoke(core.clj:5865) at clojure.lang.RestFn.invoke(RestFn.java:408) at clojure.core$load_one.invoke(core.clj:5671) at clojure.core$load_lib$fn__5397.invoke(core.clj:5711) at clojure.core$load_lib.doInvoke(core.clj:5710) at clojure.lang.RestFn.applyTo(RestFn.java:142) at clojure.core$apply.invoke(core.clj:632) at clojure.core$load_libs.doInvoke(core.clj:5753) at clojure.lang.RestFn.applyTo(RestFn.java:137) at clojure.core$apply.invoke(core.clj:634) at clojure.core$use.doInvoke(core.clj:5843) at clojure.lang.RestFn.invoke(RestFn.java:408) at org.apache.storm.command.config_value$loading__5340__auto____12530.invoke(config_value.clj:16) at org.apache.storm.command.config_value__init.load(Unknown Source) at org.apache.storm.command.config_value__init.<clinit>(Unknown Source) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:348) at clojure.lang.RT.classForName(RT.java:2154) at clojure.lang.RT.classForName(RT.java:2163) at clojure.lang.RT.loadClassForName(RT.java:2182) at clojure.lang.RT.load(RT.java:436) at clojure.lang.RT.load(RT.java:412) at clojure.core$load$fn__5448.invoke(core.clj:5866) at clojure.core$load.doInvoke(core.clj:5865) at clojure.lang.RestFn.invoke(RestFn.java:408) at clojure.lang.Var.invoke(Var.java:379) at org.apache.storm.command.config_value.<clinit>(Unknown Source) Caused by: while scanning a simple key in 'reader', line 3, column 1: storm.health.check.timeout.ms:5000 ^ could not found expected ':' in 'reader', line 4, column 1: supervisor.slots.ports: ^
the main reason for this error is that there is no space in the special location of the configuration file. However, it is difficult to solve this problem. Here is a simple and effective method. Just use vim to open the configuration file, and make all configuration content color when making changes. The correct configuration file for all color rendering is as follows:
image.png for illustration, an error use case is specially designed to compare with the correct use case. The configuration file with incomplete color rendering error is as follows:
image.png the only difference between a bad profile and a correct profile is that there is one less space before the parameter "5000".
