我想將CSV批量上傳到cassandra 2.0.3中。 現在我已成功將CSV轉換爲sstables。批量將CSV導入到Cassandra 2.0.3中
但是,當我運行sstableloader時,出現如下錯誤消息。這個錯誤影響我的bulkload,因爲我沒有在cassandra 2.0.3中找到導入的數據。
VirtualBox:~/apache-cassandra-2.0.3$ ./bin/sstableloader -d localhost airlines/flight/
ERROR 16:08:04,832 Unable to initialize MemoryMeter (jamm not specified as javaagent). This means Cassandra will be unable to measure object sizes accurately and may consequently OOM.

我有這個錯誤顯示,但正確的數據流。你加載了多少行(aprrox)? (看起來像你在做幾行,因爲速度爲0MB/s) –
