在浏览Google docs时，我在最终导出命令上获得了以下堆栈跟踪（从主实例执行并设置了适当的 env 变量）。

${HADOOP_HOME}/bin/hadoop jar ${HADOOP_BIGTABLE_JAR} export-table -libjars ${HADOOP_BIGTABLE_JAR} <table-name> <gs://bucket>

这是我设置的 ENV var，以防万一：

export HBASE_HOME=/home/hadoop/hbase-install
export HADOOP_CLASSPATH=`${HBASE_HOME}/bin/hbase classpath`
export HADOOP_HOME=/home/hadoop/hadoop-install

export HADOOP_CLIENT_OPTS="-Xbootclasspath/p:${HBASE_HOME}/lib/bigtable/alpn-boot-7.1.3.v20150130.jar"
export HADOOP_BIGTABLE_JAR=${HBASE_HOME}/lib/bigtable/bigtable-hbase-mapreduce-0.2.2-shaded.jar
export HADOOP_HBASE_JAR=${HBASE_HOME}/lib/hbase-server-1.1.2.jar

此外，当我尝试运行hbase shell然后list表格时，它只是挂起并且没有获取表格列表。这就是发生的事情：

~$ hbase shell

我试过了：

  • 仔细检查 ALPN 和 ENV 变量是否正确设置
  • 仔细检查 hbase-site.xml 和 hbase-env.sh 以确保没有任何问题。

我什至还尝试从另一个 gcloud 实例连接到我的集群（就像我以前能够遵循这些指示一样），但似乎我现在似乎也无法让它工作......（它也挂起）

我做错了什么有什么想法吗？看起来像是访问问题 - 我该如何解决？

谢谢！

  1. 您可以按照这些说明启动启用 Bigtable 的 Dataproc 集群。

  2. 通过ssh到主服务器./cluster.sh ssh

  3. hbase shell验证一切正常。

  4. hadoop jar ${HADOOP_BIGTABLE_JAR} export-table -libjars ${HADOOP_BIGTABLE_JAR} <table-name> gs://<bucket>/some-folder

  5. gsutil ls gs://<bucket>/some-folder/**并查看_SUCCESS是否存在。如果是这样，剩下的文件就是您的数据。

  6. exit从您的集群主服务器

  7. ./cluster.sh delete摆脱集群，如果您不再需要它。

您遇到了每周 Java 运行时更新的问题，该问题已得到纠正。
