引起：java.io.IOException：hive中预期的字段名称

Question

m1 <- as.matrix(data.frame(a = sample(1:10, size = 7),
                 b= sample(1:10, size = 7),
                 c=sample(1:10, size = 7),
                 d=sample(1:10, size = 7),
                 e=sample(1:10, size = 7),
                 f=sample(1:10, size = 7),
                 g=sample(1:10, size = 7)))
                 rownames(m1)<-colnames(m1)


m2 <- as.matrix(data.frame(a = sample(1:10, size = 7),
                 b= sample(1:10, size = 7),
                 c=sample(1:10, size = 7),
                 d=sample(1:10, size = 7),
                 e=sample(1:10, size = 7),
                 f=sample(1:10, size = 7),
                 g=sample(1:10, size = 7)))
                 rownames(m2)<-colnames(m2)



df <- data.frame(N = as.factor(letters[1:7]), 
       V = c("v1","v2","v3","v1","v2","v3","v1"))

我使用过json serde（ROW FORMAT SERDE'org.apache.hive.hcatalog.data.JsonSerDe'）;创建表格，同一个表格适用于较小的测试数据集。
