有人能帮助我吗？ :(

主机上的/ tmp目录对于cassandra希望创建的临时文件来说还不够大，临时文件与系统中的数据量有关，因为现在的数据库比它大在过去，它才开始，但它不从现在开始。

检查用df/tmp目录的状态。这是我的系统

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

改变这种用于这些地方临时文件，如错误说set java.io.tmpdir 在我的系统（Ubuntu Linux）上，可以通过编辑文件末尾/etc/cassandra/cassandra-env.sh

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

确保新的临时目录有足够的空间，并且权限是正确的，可能允许读取卡桑德拉用户/写

感谢就足够了，我想清楚了我的tmp文件，但idon不知道它的目录，我清除sda1文件，但仍然当我使用cqlsh得到相同的erorr – zsh
