Cassandra düğümünü yeniden başlatmadan bir sstable'ı nasıl yeniden yapabilirim?

Question

i bir düğüm üzerinde kompakt bir iş yapmak var, excepitons izleyin atar:

bu yüzden, ben onarım yapmak daha sstable cassandra_uc_log-LOG_USER-ka-7611-Data.db silmek, ama bir atar yeni excepiton:

 
Repair session f33a4b10-ffb7-11e5-8fe3-31b2e5b5b0b2 for range (-5651751204441903619,-5621122634670931727] failed with error java.io.IOException: Failed during snapshot creation. 

nasıl tamir veya sstable cassandra_uc_log-LOG_USER-ka-7611-Data.db

Answer 1

Ben silinen dosya ile düğüm yeniden gerekecek korkuyorum yeniden oluşturabilirsiniz. Bir dahaki sefere nodetool scrub'u bozuk sstable ile birlikte çalıştırabilirsiniz.

Cassandra sürümünüzden bahsetmediniz, ancak Cassandra 2.1+ ile artımlı onarımlar kullandığınızı varsayarak, sstable'ın zaten onarılmış durumda olması durumunda tam bir onarım yapmanız gerekebilir.
