cassandra連接錯誤：無法連接到localhost：9160

我的cassandra工作正常，但突然停止工作！當我使用cqlsh命令我得到這個錯誤：連接錯誤：無法連接到本地主機：9160 和output.log文件我看到的是：cassandra連接錯誤：無法連接到localhost：9160

    Try using the -Djava.io.tmpdir= option to select an alternate temp location.

有人能幫助我嗎？ :(

主機上的/ tmp目錄對於cassandra希望創建的臨時文件來說還不夠大，臨時文件與系統中的數據量有關，因爲現在的數據庫比它大在過去，它纔開始，但它不從現在開始。

檢查用df/tmp目錄的狀態。這是我的系統

$ df /tmp 
Filesystem  1K-blocks  Used Available Use% Mounted on 
/dev/sda6  570881944 350121276 191761552 65%/

改變這種用於這些地方臨時文件，如錯誤說set java.io.tmpdir 在我的系統（Ubuntu Linux）上，可以通過編輯文件末尾/etc/cassandra/cassandra-env.sh

JVM_OPTS="$JVM_OPTS $JVM_EXTRA_OPTS -Djava.io.tmpdir=/opt"

確保新的臨時目錄有足夠的空間，並且權限是正確的，可能允許讀取卡桑德拉用戶/寫

感謝就足夠了，我想清楚了我的tmp文件，但idon不知道它的目錄，我清除sda1文件，但仍然當我使用cqlsh得到相同的erorr – zsh
