java - Cassandra 2.2.8 : sstableverify - GC overhead limit exceeded

Question

我怀疑我损坏了表的 sstables，因此我在节点关闭时运行 sstableverify 实用程序。我收到类似 [超出 GC 开销限制]

的消息

如果可以解决或解决此问题，请寻求帮助..提前致谢!

sstableverify -v enterprise ale_state_access_point

我猜你有很多 sstables，因为它仅仅构建描述符就失败了。如果系统上有内存，请尝试增加堆(默认 256mb):

MAX_HEAP_SIZE=4G sstableverify -v enterprise ale_state_access_point
