为什么最新版本的 apache-cassandra 中没有 class CqlStorage-X.X.X.jar
Why the class CqlStorage is not there in latest versions of apache-cassandra-X.X.X.jar
classorg.apache.cassandra.hadoop.pig.CqlStorage是个猪Cassandra驱动。
此 class 存在于以下 Cassandra 版本中，
- 2.0.5 (apache-cassandra-2.0.5.jar)
- 2.1.12 (apache-cassandra-2.1.12.jar)
但在后续最新版本中缺少它
- 2.2.4 (apache-cassandra-2.2.4.jar)
- 3.0.0 (apache-cassandra-3.0.0-alpha1.jar)
不确定为什么停产以及相同的替代品是什么。
在这里查看关于它的 JIRA -- https://issues.apache.org/jira/browse/CASSANDRA-10542
Nobody's currently responsible for Pig code. As a result, there is nobody to fix the issues, or even fix the failing tests (of which we unfortunately have plenty). Those tests take time to run, constantly hang, and fail with cryptic errors that we don't know how to fix and don't have enough resources to investigate.
Thus I propose we deprecate Pig support in 2.2 and remove it in 3.0.
