这是一个关于 etcd（分布式键值存储系统）的警告日志。日志中提到，etcd 的 leader（领导者）在发送心跳信号时出现了失败。心跳信号是 leader 用来维持与其他节点的通信并确保集群的稳定性的重要机制之一。这个警告可能暗示着某些网络问题或者 etcd 集群出现了故障。建议你检查网络连接以及 etcd 集群的状态，以便排除问题并恢复正常运行。

UserWarning: The gensim.similarities.levenshtein submodule is disabled, because the optional Levenshtein package <https://pypi.org/project/python-Levenshtein/> is unavailable.

If you need to lemmatize, use e.g. <https://github.com/clips/pattern>. Perform lemmatization as part of your tokenization function and pass it as the tokenizer_func parameter to this initializer.报错原因

这个错误是因为gensim.similarities.levenshtein子模块需要一个名为python-Levenshtein的可选包。如果您不安装这个可选包，它将被禁用，并会显示上述警告消息。

如果您需要使用这个子模块，可以按照警告消息中提供的建议安装python-Levenshtein包来解决问题：

pip install python-Levenshtein

如果您不需要使用这个子模块，可以忽略警告消息。

你的 Sqoop 命令中有一些语法错误，导致无法正确解析参数。具体来说，你在 --query 参数中使用了 and 和 id=1，这两个是不合法的参数。同时，你也没有正确设置 --fields-terminated-by 参数，应该使用 \t 而非 "\t"。最后，-m 参数后应该跟一个数字，表示并发导入的数量。以下是修改后的命令：

bin/sqoop import \
--connect jdbc:mysql://192.168.88.132:3306/meta_erp_data \
--username root \
--password 666666 \
--table dim_car_time \
--hive-import \
--hive-database ods \
--hive-table ods_dim_car_time_s99 \
--query "select id,mdate from dim_car_time where \$CONDITIONS and id=1" \
--hive-overwrite \
--fields-terminated-by '\t' \
