插入运行我的单元测试时，一些行插入我的BigQuery资料表今天我面对这个错误行

Question

写入时的数据不足：

我认为它的新版本，是因为谷歌，基于HTTP客户端（1.16.0.rc），因为在运行测试之前我已更新。但回滚到1.15.0-rc不起作用。

有什么想法？

Answer 1

当我将大文件插入Google云存储时，我遇到了与google-http-client（1.16.0.rc）类似的问题。我认为原因也可能是一样的。

Answer 2

我也是。此外，它似乎是一个迹象，Bigquery刚刚停止接收任何数据。因为如果你在这个异常之后按count（*）查询你的表，结果将不会再改变。如果我把我的程序运行了一段时间，它会给我的错误，如：

javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake 
at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:973) 
at sun.security.ssl.SSLSocketImpl.performInitialHandshake(SSLSocketImpl.java:1343) 
at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1371) 
at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1355) 

等待答案......当出现通信故障，特别是对于大文件

Answer 3

这些错误通常发生。 避免它的方法是to use resumable upload。
