Github user lingjinjiang commented on the issue: https://github.com/apache/flink/pull/3711 Hi @greghogan , In the config.sh, there is a if statement identifies whether HBASE_CONF_DIR is setted. If the HBASE_CONF_DIR is setted, then will use the "hbase classpath" command to add the hbase's classpath to flink's classpath. But it does not check whether the "hbase" command is existed before using it. Then in the host where I'm using flink, another application need this env variable and there is no "hbase" command, then the error happen.
