报错情况1.开启并行set enable_parallel_outfile = true;后，导出报错：
detailMessage = unknown compression type(2291)，不开启时正常。表压缩类型为zstd。
2.报错提示：
RpcException, msg: org.apache.doris.rpc.RpcException: failed to send brpc batch, error=Host is down, error_text=[E1014]Got EOF of Socket{id=1167 fd=392 addr=ip:80611:642944} (0x0x7f86da482400) [R1][E112]Not connected to ip:80611 yet
3.报错提示：detailMessage = 4090625 have no queryable replicas. err: 4090627's backend 10003 does not exist or not alive, 4090626's backend 1238956 does not exist or not alive。
注：表查询select* from tab都会报错。之前查询正常，该情况突然出现的。
