我们已经设置了一个小型Spark群集,我们正在测试它是否可以从HDFS读取。我们正在测试一个只从HDFS读取的小作业,并将读取文件中的行数写入stdout。
使用本地主服务器(local[*]
)运行时,此方法正常。
但是,当尝试将作业提交到Mesos(mesos://zk://host1:2181,host2:2181,host3:2181/mesos
)时,我们会收到以下错误:

所有Spark节点都具有相同版本的Hadoop库(2.6.0)和相同的配置。我已经手动检查了类是否存在,还通过在Spark Shell中使用Class.forName(...)
进行测试。
我们使用Kerberos进行身份验证,并且所有节点都有一个有效的Kerberos票证供您阅读。
我们正在运行Spark 1.5.1。
欢迎任何建议。
