【问题描述】：
执行 DataFlow 管道时，我们偶尔会看到这些异常。我们能对他们做些什么吗？我们有一个非常简单的流程，它从 BigQuery 查询中读取数据并在 BigTable 中填充数据。
此外，管道内的数据会发生什么情况？是否经过再加工？还是在传输到 BigTable 的过程中丢失了？
CloudBigtableIO.initializeForWrite(p);
p.apply(BigQueryIO.Read.fromQuery(getQuery()))
.apply(ParDo.of(new DoFn<TableRow, Mutation>() {
public void processElement(ProcessContext c) {
Mutation output = convertDataToRow(c.element());
c.output(output);
}
}))
.apply(CloudBigtableIO.writeToTable(config));
private static Mutation convertDataToRow(TableRow element) {
LOG.info("element: "+ element);
LOG.info("BASM_segment_id: "+ element.get("BASM_segment_id"));
if(element.get("BASM_AID") != null){
Put obj = new Put(getRowKey(element).getBytes()).addColumn(SEGMENT_FAMILY, SEGMENT_COLUMN_NAME, ((String)element.get("BAS_category")).getBytes() );
obj.addColumn(USER_FAMILY, "AID".getBytes(), ((String)element.get("BASM_AID")).getBytes());
if(element.get("BASM_segment_id") != null){
obj.addColumn(SEGMENT_FAMILY, "segment_id".getBytes(), ((String)element.get("BASM_segment_id")).getBytes());
}
if(element.get("BAS_sub_category") != null){
obj.addColumn(SEGMENT_FAMILY, "sub_category".getBytes(), ((String)element.get("BAS_sub_category")).getBytes());
}
if(element.get("BAS_name") != null){
obj.addColumn(SEGMENT_FAMILY, "name".getBytes(), ((String)element.get("BAS_name")).getBytes());
}
if(element.get("BAS_description") != null){
obj.addColumn(SEGMENT_FAMILY, "description".getBytes(), ((String)element.get("BAS_description")).getBytes());
}
if(element.get("BAS_last_compute_day") != null){obj.addColumn(USER_FAMILY, "Krux_User_id".getBytes(), ((String)element.get("BASM_krux_user_id")).getBytes());
obj.addColumn(SEGMENT_FAMILY, "last_compute_day".getBytes(), ((String)element.get("BAS_last_compute_day")).getBytes());
}
if(element.get("BAS_type") != null){
obj.addColumn(SEGMENT_FAMILY, "type".getBytes(), ((String)element.get("BAS_type")).getBytes());
}
if(element.get("BASM_REGID") != null){
obj.addColumn(USER_FAMILY, "REGID".getBytes(), ((String)element.get("BASM_REGID")).getBytes() );
}
return obj;
}else{
return null;
}
}
以下是我们得到的异常：

【问题讨论】：
-
您使用的是什么版本的客户端？ 0.9.1?
-
@LesVogel-GoogleDevRel 是的，我们正在为 bigtable-hbase-dataflow 使用 0.9.1 版本
-
我已经请工程师发表评论 - 应该是今天晚些时候。
-
您能否在日志中搜索“批量操作期间发生异常”（原文如此）？这应该会提供有关实际问题的更多信息日志。 RetriesExhaustedWithDetailsException 太笼统了。
-
您可能需要考虑： if (output != null) { c.output(output); };这种类型的异常可能发生在空值中。
