鎖定來自HiveContext的Hive表

Question

我們正在根據數據倉庫的需求設置配置單元，並在配置單元作為存儲時使用spark進行處理。 我們的文件很小（<10KB），但數量很大。 要求是幾乎實時地提供數據。 因此，我的方法每個都在配置單元上創建一個分區以指示其當前或過去。 保持最新發布的數據，但經過一定的時間間隔后將其聚合並移至分區PAST。 但是在進行移動操作時，我需要鎖定表，因為它可能會提供不正確的數據。

對於配置單元CLI沒有問題。

hive> LOCK TABLE t26013_75 exclusive;
OK
Time taken: 0.106 seconds

但是當我嘗試相同的火花

Answer 1

我更仔細地觀看了日志並在添加以下內容后得到修復

scala> hiveContext.setConf("hive.support.concurrency","true")

我不知道為什么要問。 我已經在hive / conf位置中有了hive-site.xml。

可能是因為我在spark / conf上的hive-site.xml剛剛輸入了以下內容

<configuration>
<property>
  <name>hive.metastore.uris</name>
  <value>thrift://localhost:9083</value>
</property>

將會看到，將來可能還會在spark / conf / hive-site.xml中添加此參數

謝謝你的時間。
