在Hive中遇到中文乱码的问题，可能是因为Hive默认使用的编码方式不是UTF-8，导致无法正确存储和显示中文字符。解决方法如下：
在创建表时指定字符集为UTF-8：CREATE TABLE table_name ( column1 STRING, column2 INT)ROW FORMAT DELIMITEDFIELDS TERMINATED BY ','STORED AS TEXTFILETBLPROPERTIES ("charset"="utf8");<property> <name>hive.default.charset</name> <value>utf8</value></property>SET hive.cli.print.header=true;SET hive.cli.print.current.db=true;SET hive.cli.print.header=true;SET hive.cli.print.current.db=true;SET hive.resultset.use.unique.column.names=false;SET mapred.reduce.tasks=1;SET hive.metastore.warehouse.dir=/user/hive/warehouse;SET hive.support.concurrency=false;SET hive.enforce.bucketing=true;SET hive.exec.dynamic.partition.mode=nonstrict;SET hive.txn.manager=org.apache.hadoop.hive.ql.lockmgr.DbTxnManager;SET hive.exec.dynamic.partition.mode=nonstrict;SET hive.exec.dynamic.partition=true;SET hive.exec.dynamic.partition.mode=nonstrict;SET hive.execution.engine=tez;SET hive.execution.engine=mr;SET hive.exec.parallel=true;SET hive.exec.compress.output=true;SET hive.exec.compress.intermediate=true;SET hive.exec.reducers.bytes.per.reducer=128000000;SET hive.exec.reducers.max=1099;SET hive.exec.reducers.min=1;SET mapred.reduce.tasks=8;SET mapred.map.tasks=8;SET mapred.max.split.size=268435456;SET hive.exec.max.dynamic.partitions=100000;SET hive.exec.max.dynamic.partitions.pernode=100000;SET hive.exec.max.created.files=100000;SET mapreduce.job.queuename=default;SET hive.exec.submitviachild=true;SET hive.downloaded.resources.dir=/tmp/$USER/hive_resources;SET hive.scratch.dir=/tmp/$USER/hive_scratch;SET hive.server2.enable.impersonation=true;SET hive.mapred.local.mode=true;SET hive.auto.convert.join=true;SET hive.mapjoin.smalltable.filesize=25000000;SET hive.auto.convert.join.noconditionaltask=true;SET hive.compute.query.using.stats=true;SET hive.stats.fetch.column.stats=true;SET hive.stats.fetch.partition.stats=true;SET hive.security.authorization.sqlstd.confwhitelist.append=false;SET hive.strict.checks.large.query=true;SET hive.stats.autogather=true;SET hive.stats.autogather=true;SET hive.compute.query.using.stats=true;SET hive.stats.fetch.column.stats=true;SET hive.stats.fetch.partition.stats=true;SET hive.security.authorization.sqlstd.confwhitelist.append=false;SET hive.strict.checks.large.query=true;SET hive.exec.reducers.max=1099;SET hive.security.authorization.enabled=false;SET hive.cli.print.header=true;SET hive.cli.print.current.db=true;SET hive.mapred.reduce.tasks=1;SET hive.metastore.warehouse.dir=/user/hive/warehouse;SET hive.support.concurrency=false;SET hive.enforce.bucketing=true;SET hive.txn.manager=org.apache.hadoop.hive.ql.lockmgr.DbTxnManager;SET hive.exec.dynamic.partition.mode=nonstrict;SET hive.exec.dynamic.partition=true;SET hive.exec.dynamic.partition.mode=nonstrict;SET hive.execution.engine=tez;SET hive.execution.engine=mr;SET hive.exec.parallel=true;SET hive.exec.compress.output=true;SET hive.exec.compress.intermediate=true;SET hive.exec.reducers.bytes.per.reducer=128000000;SET hive.exec.reducers.max=1099;SET hive.exec.reducers.min=1;SET mapred.reduce.tasks=8;SET mapred.map.tasks=8;SET mapred.max.split.size=268435456;SET hive.exec.max.dynamic.partitions=100000;SET hive.exec.max.dynamic.partitions.pernode=100000;SET hive.exec.max.created.files=100000;SET mapreduce.job.queuename=default;SET hive.exec.submitviachild=true;SET hive.downloaded.resources.dir=/tmp/$USER/hive_resources;SET hive.scratch.dir=/tmp/$USER/hive_scratch;SET hive.server2.enable.impersonation=true;SET hive.mapred.local.mode=true;SET hive.auto.convert.join=true;SET hive.mapjoin.smalltable.filesize=25000000;SET hive.auto.convert.join.noconditionaltask=true;SET hive.compute.query.using.stats=true;SET hive.stats.fetch.column.stats=true;SET hive.stats.fetch.partition.stats=true;SET hive.security.authorization
