Question

尝试使用HBase Java客户端扫描有1.3亿行的Bigtable。扫描几个小时后，它抛出：

INFO com.google.cloud.bigtable.grpc.async.AbstractRetryingOperation - Retrying failed call. Failure #1, got: Status{code=DEADLINE_EXCEEDED, description=Error while reading table '', cause=null} on channel 5.

有一些此类异常可以重试，但最终导致：

快速更新：这两个问题均已在1.9.0版中修复

对1.3亿行进行大表扫描会引发java.lang.IllegalStateException：未启动
